Given numbers are 628, 968, 357, 820
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(628, 968) = 151976
GCD(628, 968) = ( 628 x 968 ) / 151976
= 628 / 968
= 628
Step2:
LCM(4, 357) = 1428
GCD(4, 357) = ( 4 x 357 ) / 1428
= 4 / 357
= 4
Step3:
LCM(1, 820) = 820
GCD(1, 820) = ( 1 x 820 ) / 820
= 1 / 820
= 1
So, Greatest Common Divisor of 628, 968, 357, 820 is 1
