Given numbers are 423, 648, 429, 956
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(423, 648) = 30456
GCD(423, 648) = ( 423 x 648 ) / 30456
= 423 / 648
= 423
Step2:
LCM(9, 429) = 1287
GCD(9, 429) = ( 9 x 429 ) / 1287
= 9 / 429
= 9
Step3:
LCM(3, 956) = 2868
GCD(3, 956) = ( 3 x 956 ) / 2868
= 3 / 956
= 3
So, Greatest Common Divisor of 423, 648, 429, 956 is 1
