Given numbers are 645, 152, 495, 986

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 152 are 2 x 2 x 2 x 19

Prime factors of 495 are 3 x 3 x 5 x 11

Prime factors of 986 are 2 x 17 x 29

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

Given numbers are 645, 152, 495, 986

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

Apply this formula for all numbers.

Step1:

LCM(645, 152) = 98040

GCD(645, 152) = ( 645 x 152 ) / 98040

= 645 / 152

= 645

Step2:

LCM(1, 495) = 495

GCD(1, 495) = ( 1 x 495 ) / 495

= 1 / 495

= 1

Step3:

LCM(1, 986) = 986

GCD(1, 986) = ( 1 x 986 ) / 986

= 1 / 986

= 1

So, Greatest Common Divisor of 645, 152, 495, 986 is 1
