GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 127) = 81153
GCD(639, 127) = ( 639 x 127 ) / 81153
= 639 / 127
= 639
Step2:
LCM(1, 813) = 813
GCD(1, 813) = ( 1 x 813 ) / 813
= 1 / 813
= 1
Step3:
LCM(1, 929) = 929
GCD(1, 929) = ( 1 x 929 ) / 929
= 1 / 929
= 1
So, Greatest Common Divisor of 639, 127, 813, 929 is 1
