Given numbers are 623, 912, 447, 429
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(623, 912) = 568176
GCD(623, 912) = ( 623 x 912 ) / 568176
= 623 / 912
= 623
Step2:
LCM(1, 447) = 447
GCD(1, 447) = ( 1 x 447 ) / 447
= 1 / 447
= 1
Step3:
LCM(1, 429) = 429
GCD(1, 429) = ( 1 x 429 ) / 429
= 1 / 429
= 1
So, Greatest Common Divisor of 623, 912, 447, 429 is 1
