Given numbers are 560, 145, 86, 620

The list of prime factors of all numbers are

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

Prime factors of 145 are 5 x 29

Prime factors of 86 are 2 x 43

Prime factors of 620 are 2 x 2 x 5 x 31

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

Given numbers are 560, 145, 86, 620

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

Apply this formula for all numbers.

Step1:

LCM(560, 145) = 16240

GCD(560, 145) = ( 560 x 145 ) / 16240

= 560 / 145

= 560

Step2:

LCM(5, 86) = 430

GCD(5, 86) = ( 5 x 86 ) / 430

= 5 / 86

= 5

Step3:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

So, Greatest Common Divisor of 560, 145, 86, 620 is 1
