Given numbers are 640, 824, 359, 545

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

Apply this formula for all numbers.

Step1:

LCM(640, 824) = 65920

GCD(640, 824) = ( 640 x 824 ) / 65920

= 640 / 824

= 640

Step2:

LCM(8, 359) = 2872

GCD(8, 359) = ( 8 x 359 ) / 2872

= 8 / 359

= 8

Step3:

LCM(1, 545) = 545

GCD(1, 545) = ( 1 x 545 ) / 545

= 1 / 545

= 1

So, Greatest Common Divisor of 640, 824, 359, 545 is 1
