GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(421, 771) = 324591
GCD(421, 771) = ( 421 x 771 ) / 324591
= 421 / 771
= 421
Step2:
LCM(1, 659) = 659
GCD(1, 659) = ( 1 x 659 ) / 659
= 1 / 659
= 1
Step3:
LCM(1, 461) = 461
GCD(1, 461) = ( 1 x 461 ) / 461
= 1 / 461
= 1
So, Greatest Common Divisor of 421, 771, 659, 461 is 1
