GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(272, 644) = 43792
GCD(272, 644) = ( 272 x 644 ) / 43792
= 272 / 644
= 272
Step2:
LCM(4, 669) = 2676
GCD(4, 669) = ( 4 x 669 ) / 2676
= 4 / 669
= 4
Step3:
LCM(1, 970) = 970
GCD(1, 970) = ( 1 x 970 ) / 970
= 1 / 970
= 1
So, Greatest Common Divisor of 272, 644, 669, 970 is 1
