Given numbers are 902, 207, 506, 640

The list of prime factors of all numbers are

Prime factors of 902 are 2 x 11 x 41

Prime factors of 207 are 3 x 3 x 23

Prime factors of 506 are 2 x 11 x 23

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 902, 207, 506, 640

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

Apply this formula for all numbers.

Step1:

LCM(902, 207) = 186714

GCD(902, 207) = ( 902 x 207 ) / 186714

= 902 / 207

= 902

Step2:

LCM(1, 506) = 506

GCD(1, 506) = ( 1 x 506 ) / 506

= 1 / 506

= 1

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 902, 207, 506, 640 is 1
