Given numbers are 492, 687, 369, 638
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(492, 687) = 112668
GCD(492, 687) = ( 492 x 687 ) / 112668
= 492 / 687
= 492
Step2:
LCM(3, 369) = 369
GCD(3, 369) = ( 3 x 369 ) / 369
= 3 / 369
= 3
Step3:
LCM(3, 638) = 1914
GCD(3, 638) = ( 3 x 638 ) / 1914
= 3 / 638
= 3
So, Greatest Common Divisor of 492, 687, 369, 638 is 1
