GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(648, 178) = 57672
GCD(648, 178) = ( 648 x 178 ) / 57672
= 648 / 178
= 648
Step2:
LCM(2, 421) = 842
GCD(2, 421) = ( 2 x 421 ) / 842
= 2 / 421
= 2
Step3:
LCM(1, 885) = 885
GCD(1, 885) = ( 1 x 885 ) / 885
= 1 / 885
= 1
So, Greatest Common Divisor of 648, 178, 421, 885 is 1
