Given numbers are 355, 181, 640, 634

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

Apply this formula for all numbers.

Step1:

LCM(355, 181) = 64255

GCD(355, 181) = ( 355 x 181 ) / 64255

= 355 / 181

= 355

Step2:

LCM(1, 640) = 640

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

= 1 / 640

= 1

Step3:

LCM(1, 634) = 634

GCD(1, 634) = ( 1 x 634 ) / 634

= 1 / 634

= 1

So, Greatest Common Divisor of 355, 181, 640, 634 is 1
