Given numbers are 128, 871, 780, 192
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(128, 871) = 111488
GCD(128, 871) = ( 128 x 871 ) / 111488
= 128 / 871
= 128
Step2:
LCM(1, 780) = 780
GCD(1, 780) = ( 1 x 780 ) / 780
= 1 / 780
= 1
Step3:
LCM(1, 192) = 192
GCD(1, 192) = ( 1 x 192 ) / 192
= 1 / 192
= 1
So, Greatest Common Divisor of 128, 871, 780, 192 is 1
