Given numbers are 174, 689, 643, 730
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(174, 689) = 119886
GCD(174, 689) = ( 174 x 689 ) / 119886
= 174 / 689
= 174
Step2:
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
= 1 / 643
= 1
Step3:
LCM(1, 730) = 730
GCD(1, 730) = ( 1 x 730 ) / 730
= 1 / 730
= 1
So, Greatest Common Divisor of 174, 689, 643, 730 is 1
