Given numbers are 411, 137, 304, 643
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(411, 137) = 411
GCD(411, 137) = ( 411 x 137 ) / 411
= 411 / 137
= 411
Step2:
LCM(137, 304) = 41648
GCD(137, 304) = ( 137 x 304 ) / 41648
= 137 / 304
= 137
Step3:
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
= 1 / 643
= 1
So, Greatest Common Divisor of 411, 137, 304, 643 is 1
