GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(178, 624) = 55536
GCD(178, 624) = ( 178 x 624 ) / 55536
= 178 / 624
= 178
Step2:
LCM(2, 921) = 1842
GCD(2, 921) = ( 2 x 921 ) / 1842
= 2 / 921
= 2
Step3:
LCM(1, 810) = 810
GCD(1, 810) = ( 1 x 810 ) / 810
= 1 / 810
= 1
So, Greatest Common Divisor of 178, 624, 921, 810 is 1
