The GCF is 5.

The GCF is 5.

The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 520 and 720 is 40

The GCF is 8.

The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 140, 340, and 520 is 20

The greatest common factor of 220 and 520 is 20.220: 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220520: 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

The Greatest Common Divisor (GCD) for 520 and 546 is 26.

520/390 taking 130 as common factor = 4:3

The greatest common factor (GCF) of 45 and 20 is 5.Prime factors:45 = 5Ã—3Ã—320 = 5Ã—2Ã—2the only prime factor in both is 5, and so the highest common factor is 5.Alternative method:45 mod 20 = 520 mod 5 = 0so HCF = 5.

To find the greatest common factor, list the prime factors of each number:40: 2 x 2 x 2 x 520: 2 x 2 x 5Then select the factors that each share:2 x 2 x 5 (they each share these individual numbers)So, the greatest common factor is 20.Since 20 is a factor of 40, it is automatically the GCF.

520. 13 is a prime number and not a factor of 40.

The least common multiple of 20, 8, 20, and 520 is 520.

Since 65 is a factor of 520, it is automatically the GCF.

520 = 1 x 520 520 = 2 x 260 520 = 4 x 130 520 = 5 x 104 520 = 8 x 65 520 = 10 x 52 520 = 13 x 40 520 = 20 x 26

520 / \ 2 260 / \ 130 2 / \ 65 2 / \ 5 13

2 x 2 x 2 x 5 x 13 = 520

Least Common Multiple (LCM) for 360 520 is 4,680.
