Given numbers are 156, 380, 639, 512

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

Apply this formula for all numbers.

Step1:

LCM(156, 380) = 14820

GCD(156, 380) = ( 156 x 380 ) / 14820

= 156 / 380

= 156

Step2:

LCM(4, 639) = 2556

GCD(4, 639) = ( 4 x 639 ) / 2556

= 4 / 639

= 4

Step3:

LCM(1, 512) = 512

GCD(1, 512) = ( 1 x 512 ) / 512

= 1 / 512

= 1

So, Greatest Common Divisor of 156, 380, 639, 512 is 1
