Given numbers are 346, 693, 655, 638
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(346, 693) = 239778
GCD(346, 693) = ( 346 x 693 ) / 239778
= 346 / 693
= 346
Step2:
LCM(1, 655) = 655
GCD(1, 655) = ( 1 x 655 ) / 655
= 1 / 655
= 1
Step3:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
So, Greatest Common Divisor of 346, 693, 655, 638 is 1
