GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(166, 698) = 57934
GCD(166, 698) = ( 166 x 698 ) / 57934
= 166 / 698
= 166
Step2:
LCM(2, 517) = 1034
GCD(2, 517) = ( 2 x 517 ) / 1034
= 2 / 517
= 2
Step3:
LCM(1, 391) = 391
GCD(1, 391) = ( 1 x 391 ) / 391
= 1 / 391
= 1
So, Greatest Common Divisor of 166, 698, 517, 391 is 1
