Given numbers are 457, 342, 299, 921
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(457, 342) = 156294
GCD(457, 342) = ( 457 x 342 ) / 156294
= 457 / 342
= 457
Step2:
LCM(1, 299) = 299
GCD(1, 299) = ( 1 x 299 ) / 299
= 1 / 299
= 1
Step3:
LCM(1, 921) = 921
GCD(1, 921) = ( 1 x 921 ) / 921
= 1 / 921
= 1
So, Greatest Common Divisor of 457, 342, 299, 921 is 1
