GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(657, 231) = 50589
GCD(657, 231) = ( 657 x 231 ) / 50589
= 657 / 231
= 657
Step2:
LCM(3, 212) = 636
GCD(3, 212) = ( 3 x 212 ) / 636
= 3 / 212
= 3
Step3:
LCM(1, 980) = 980
GCD(1, 980) = ( 1 x 980 ) / 980
= 1 / 980
= 1
So, Greatest Common Divisor of 657, 231, 212, 980 is 1
