GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(708, 438) = 51684
GCD(708, 438) = ( 708 x 438 ) / 51684
= 708 / 438
= 708
Step2:
LCM(6, 436) = 1308
GCD(6, 436) = ( 6 x 436 ) / 1308
= 6 / 436
= 6
Step3:
LCM(2, 638) = 638
GCD(2, 638) = ( 2 x 638 ) / 638
= 2 / 638
= 2
So, Greatest Common Divisor of 708, 438, 436, 638 is 2
