Given numbers are 633, 285, 646, 955
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(633, 285) = 60135
GCD(633, 285) = ( 633 x 285 ) / 60135
= 633 / 285
= 633
Step2:
LCM(3, 646) = 1938
GCD(3, 646) = ( 3 x 646 ) / 1938
= 3 / 646
= 3
Step3:
LCM(1, 955) = 955
GCD(1, 955) = ( 1 x 955 ) / 955
= 1 / 955
= 1
So, Greatest Common Divisor of 633, 285, 646, 955 is 1
