Given numbers are 646, 504, 938, 381
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(646, 504) = 162792
GCD(646, 504) = ( 646 x 504 ) / 162792
= 646 / 504
= 646
Step2:
LCM(2, 938) = 938
GCD(2, 938) = ( 2 x 938 ) / 938
= 2 / 938
= 2
Step3:
LCM(2, 381) = 762
GCD(2, 381) = ( 2 x 381 ) / 762
= 2 / 381
= 2
So, Greatest Common Divisor of 646, 504, 938, 381 is 1
