Given numbers are 628, 749, 211, 715

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

Apply this formula for all numbers.

Step1:

LCM(628, 749) = 470372

GCD(628, 749) = ( 628 x 749 ) / 470372

= 628 / 749

= 628

Step2:

LCM(1, 211) = 211

GCD(1, 211) = ( 1 x 211 ) / 211

= 1 / 211

= 1

Step3:

LCM(1, 715) = 715

GCD(1, 715) = ( 1 x 715 ) / 715

= 1 / 715

= 1

So, Greatest Common Divisor of 628, 749, 211, 715 is 1
