GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(462, 126) = 1386
GCD(462, 126) = ( 462 x 126 ) / 1386
= 462 / 126
= 462
Step2:
LCM(42, 429) = 6006
GCD(42, 429) = ( 42 x 429 ) / 6006
= 42 / 429
= 42
Step3:
LCM(3, 820) = 2460
GCD(3, 820) = ( 3 x 820 ) / 2460
= 3 / 820
= 3
So, Greatest Common Divisor of 462, 126, 429, 820 is 1
