Given numbers are 628, 444, 389, 151

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

Apply this formula for all numbers.

Step1:

LCM(628, 444) = 69708

GCD(628, 444) = ( 628 x 444 ) / 69708

= 628 / 444

= 628

Step2:

LCM(4, 389) = 1556

GCD(4, 389) = ( 4 x 389 ) / 1556

= 4 / 389

= 4

Step3:

LCM(1, 151) = 151

GCD(1, 151) = ( 1 x 151 ) / 151

= 1 / 151

= 1

So, Greatest Common Divisor of 628, 444, 389, 151 is 1
