GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(432, 856) = 46224
GCD(432, 856) = ( 432 x 856 ) / 46224
= 432 / 856
= 432
Step2:
LCM(8, 991) = 7928
GCD(8, 991) = ( 8 x 991 ) / 7928
= 8 / 991
= 8
Step3:
LCM(1, 756) = 756
GCD(1, 756) = ( 1 x 756 ) / 756
= 1 / 756
= 1
So, Greatest Common Divisor of 432, 856, 991, 756 is 1
