Given numbers are 357, 417, 639, 758
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(357, 417) = 49623
GCD(357, 417) = ( 357 x 417 ) / 49623
= 357 / 417
= 357
Step2:
LCM(3, 639) = 639
GCD(3, 639) = ( 3 x 639 ) / 639
= 3 / 639
= 3
Step3:
LCM(3, 758) = 2274
GCD(3, 758) = ( 3 x 758 ) / 2274
= 3 / 758
= 3
So, Greatest Common Divisor of 357, 417, 639, 758 is 1
