Given numbers are 432, 472, 421, 678
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(432, 472) = 25488
GCD(432, 472) = ( 432 x 472 ) / 25488
= 432 / 472
= 432
Step2:
LCM(8, 421) = 3368
GCD(8, 421) = ( 8 x 421 ) / 3368
= 8 / 421
= 8
Step3:
LCM(1, 678) = 678
GCD(1, 678) = ( 1 x 678 ) / 678
= 1 / 678
= 1
So, Greatest Common Divisor of 432, 472, 421, 678 is 1
