GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(658, 238) = 11186
GCD(658, 238) = ( 658 x 238 ) / 11186
= 658 / 238
= 658
Step2:
LCM(14, 429) = 6006
GCD(14, 429) = ( 14 x 429 ) / 6006
= 14 / 429
= 14
Step3:
LCM(1, 665) = 665
GCD(1, 665) = ( 1 x 665 ) / 665
= 1 / 665
= 1
So, Greatest Common Divisor of 658, 238, 429, 665 is 1
