GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(847, 128) = 108416
GCD(847, 128) = ( 847 x 128 ) / 108416
= 847 / 128
= 847
Step2:
LCM(1, 419) = 419
GCD(1, 419) = ( 1 x 419 ) / 419
= 1 / 419
= 1
Step3:
LCM(1, 176) = 176
GCD(1, 176) = ( 1 x 176 ) / 176
= 1 / 176
= 1
So, Greatest Common Divisor of 847, 128, 419, 176 is 1
