Given numbers are 173, 672, 811, 661
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(173, 672) = 116256
GCD(173, 672) = ( 173 x 672 ) / 116256
= 173 / 672
= 173
Step2:
LCM(1, 811) = 811
GCD(1, 811) = ( 1 x 811 ) / 811
= 1 / 811
= 1
Step3:
LCM(1, 661) = 661
GCD(1, 661) = ( 1 x 661 ) / 661
= 1 / 661
= 1
So, Greatest Common Divisor of 173, 672, 811, 661 is 1
