Given numbers are 401, 137, 680, 518
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(401, 137) = 54937
GCD(401, 137) = ( 401 x 137 ) / 54937
= 401 / 137
= 401
Step2:
LCM(1, 680) = 680
GCD(1, 680) = ( 1 x 680 ) / 680
= 1 / 680
= 1
Step3:
LCM(1, 518) = 518
GCD(1, 518) = ( 1 x 518 ) / 518
= 1 / 518
= 1
So, Greatest Common Divisor of 401, 137, 680, 518 is 1
