GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 935) = 120615
GCD(645, 935) = ( 645 x 935 ) / 120615
= 645 / 935
= 645
Step2:
LCM(5, 986) = 4930
GCD(5, 986) = ( 5 x 986 ) / 4930
= 5 / 986
= 5
Step3:
LCM(1, 387) = 387
GCD(1, 387) = ( 1 x 387 ) / 387
= 1 / 387
= 1
So, Greatest Common Divisor of 645, 935, 986, 387 is 1
