How to find the GCD?

To find the Greatest Common Divisor (GCD), you can list factors, use prime factorization, or apply the efficient Euclidean Algorithm; the Euclidean Algorithm involves repeatedly dividing the larger number by the smaller and using the remainder until you get zero, with the last non-zero remainder being the GCD. Prime factorization requires breaking numbers into primes, finding common ones, and multiplying them. 

What is the LCM of 42 and 70 using prime factorization?

Prime factorization of 42 and 70 is (2 × 3 × 7) = 21 × 31 × 71 and (2 × 5 × 7) = 21 × 51 × 71 respectively. LCM of 42 and 70 can be obtained by multiplying prime factors raised to their respective highest power, i.e. 21 × 31 × 51 × 71 = 210. Hence, the LCM of 42 and 70 by prime factorization is 210.

What is the LCM of 4 4 and 7?

What is LCM of 4 and 7? The answer to this question is 28. The LCM of 4 and 7 using various methods is shown in this article for your reference. The LCM of two non-zero integers, 4 and 7, is the smallest positive integer 28 which is divisible by both 4 and 7 with no remainder.

How do I say "I love you" in a calculator?

You can write "I love you" on a calculator by typing numbers that look like letters when the calculator is flipped upside down (like 707 for "LOL" or 37047734 for "hello") or by using specific number sequences like 143, which stands for "I love you" (1 letter, 4 letters, 3 letters). For scientific calculators, you use the ALPHA key to type the actual letters 'L', 'O', 'V', 'E', 'Y', 'U' and then flip it.
 

What is my GCD?

In mathematics, the Greatest Common Divisor (GCD) is defined as the largest positive integer that divides each of the integers. The greatest common divisor is sometimes called the Highest Common Factor (HCF) or the greatest common denominator. For example, the GCD of 8 and 12 is 4.
