Given numbers are 637, 133, 660, 461
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(637, 133) = 12103
GCD(637, 133) = ( 637 x 133 ) / 12103
= 637 / 133
= 637
Step2:
LCM(7, 660) = 4620
GCD(7, 660) = ( 7 x 660 ) / 4620
= 7 / 660
= 7
Step3:
LCM(1, 461) = 461
GCD(1, 461) = ( 1 x 461 ) / 461
= 1 / 461
= 1
So, Greatest Common Divisor of 637, 133, 660, 461 is 1
