Given numbers are 402, 390, 674, 461
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(402, 390) = 26130
GCD(402, 390) = ( 402 x 390 ) / 26130
= 402 / 390
= 402
Step2:
LCM(6, 674) = 2022
GCD(6, 674) = ( 6 x 674 ) / 2022
= 6 / 674
= 6
Step3:
LCM(2, 461) = 922
GCD(2, 461) = ( 2 x 461 ) / 922
= 2 / 461
= 2
So, Greatest Common Divisor of 402, 390, 674, 461 is 1
