Given numbers are 164, 638, 683, 402
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(164, 638) = 52316
GCD(164, 638) = ( 164 x 638 ) / 52316
= 164 / 638
= 164
Step2:
LCM(2, 683) = 1366
GCD(2, 683) = ( 2 x 683 ) / 1366
= 2 / 683
= 2
Step3:
LCM(1, 402) = 402
GCD(1, 402) = ( 1 x 402 ) / 402
= 1 / 402
= 1
So, Greatest Common Divisor of 164, 638, 683, 402 is 1
