GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(959, 518) = 70966
GCD(959, 518) = ( 959 x 518 ) / 70966
= 959 / 518
= 959
Step2:
LCM(7, 917) = 917
GCD(7, 917) = ( 7 x 917 ) / 917
= 7 / 917
= 7
Step3:
LCM(7, 690) = 4830
GCD(7, 690) = ( 7 x 690 ) / 4830
= 7 / 690
= 7
So, Greatest Common Divisor of 959, 518, 917, 690 is 1
