Given numbers are 743, 117, 110, 646
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(743, 117) = 86931
GCD(743, 117) = ( 743 x 117 ) / 86931
= 743 / 117
= 743
Step2:
LCM(1, 110) = 110
GCD(1, 110) = ( 1 x 110 ) / 110
= 1 / 110
= 1
Step3:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
So, Greatest Common Divisor of 743, 117, 110, 646 is 1
