Given numbers are 628, 708, 155, 272

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

Apply this formula for all numbers.

Step1:

LCM(628, 708) = 111156

GCD(628, 708) = ( 628 x 708 ) / 111156

= 628 / 708

= 628

Step2:

LCM(4, 155) = 620

GCD(4, 155) = ( 4 x 155 ) / 620

= 4 / 155

= 4

Step3:

LCM(1, 272) = 272

GCD(1, 272) = ( 1 x 272 ) / 272

= 1 / 272

= 1

So, Greatest Common Divisor of 628, 708, 155, 272 is 1
