GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(388, 756) = 73332
GCD(388, 756) = ( 388 x 756 ) / 73332
= 388 / 756
= 388
Step2:
LCM(4, 915) = 3660
GCD(4, 915) = ( 4 x 915 ) / 3660
= 4 / 915
= 4
Step3:
LCM(1, 196) = 196
GCD(1, 196) = ( 1 x 196 ) / 196
= 1 / 196
= 1
So, Greatest Common Divisor of 388, 756, 915, 196 is 1
