Given numbers are 724, 644, 775, 560

The list of prime factors of all numbers are

Prime factors of 724 are 2 x 2 x 181

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 775 are 5 x 5 x 31

Prime factors of 560 are 2 x 2 x 2 x 2 x 5 x 7

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 724, 644, 775, 560

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(724, 644) = 116564

GCD(724, 644) = ( 724 x 644 ) / 116564

= 724 / 644

= 724

Step2:

LCM(4, 775) = 3100

GCD(4, 775) = ( 4 x 775 ) / 3100

= 4 / 775

= 4

Step3:

LCM(1, 560) = 560

GCD(1, 560) = ( 1 x 560 ) / 560

= 1 / 560

= 1

So, Greatest Common Divisor of 724, 644, 775, 560 is 1
