GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(655, 272) = 178160
GCD(655, 272) = ( 655 x 272 ) / 178160
= 655 / 272
= 655
Step2:
LCM(1, 529) = 529
GCD(1, 529) = ( 1 x 529 ) / 529
= 1 / 529
= 1
Step3:
LCM(1, 977) = 977
GCD(1, 977) = ( 1 x 977 ) / 977
= 1 / 977
= 1
So, Greatest Common Divisor of 655, 272, 529, 977 is 1
