Given numbers are 645, 474, 138, 881
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 474) = 101910
GCD(645, 474) = ( 645 x 474 ) / 101910
= 645 / 474
= 645
Step2:
LCM(3, 138) = 138
GCD(3, 138) = ( 3 x 138 ) / 138
= 3 / 138
= 3
Step3:
LCM(3, 881) = 2643
GCD(3, 881) = ( 3 x 881 ) / 2643
= 3 / 881
= 3
So, Greatest Common Divisor of 645, 474, 138, 881 is 1
