Given numbers are 646, 746, 429, 450
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(646, 746) = 240958
GCD(646, 746) = ( 646 x 746 ) / 240958
= 646 / 746
= 646
Step2:
LCM(2, 429) = 858
GCD(2, 429) = ( 2 x 429 ) / 858
= 2 / 429
= 2
Step3:
LCM(1, 450) = 450
GCD(1, 450) = ( 1 x 450 ) / 450
= 1 / 450
= 1
So, Greatest Common Divisor of 646, 746, 429, 450 is 1
