Given numbers are 462, 156, 647, 390
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(462, 156) = 12012
GCD(462, 156) = ( 462 x 156 ) / 12012
= 462 / 156
= 462
Step2:
LCM(6, 647) = 3882
GCD(6, 647) = ( 6 x 647 ) / 3882
= 6 / 647
= 6
Step3:
LCM(1, 390) = 390
GCD(1, 390) = ( 1 x 390 ) / 390
= 1 / 390
= 1
So, Greatest Common Divisor of 462, 156, 647, 390 is 1
