Given numbers are 640, 314, 243, 179

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

Apply this formula for all numbers.

Step1:

LCM(640, 314) = 100480

GCD(640, 314) = ( 640 x 314 ) / 100480

= 640 / 314

= 640

Step2:

LCM(2, 243) = 486

GCD(2, 243) = ( 2 x 243 ) / 486

= 2 / 243

= 2

Step3:

LCM(1, 179) = 179

GCD(1, 179) = ( 1 x 179 ) / 179

= 1 / 179

= 1

So, Greatest Common Divisor of 640, 314, 243, 179 is 1
