Steps to Calculate GCD of 842, 673, 178, 991 using LCM Formula
Given numbers are 842, 673, 178, 991
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(842, 673) = 566666
GCD(842, 673) = ( 842 x 673 ) / 566666
= 842 / 673
= 842
Step2:
LCM(1, 178) = 178
GCD(1, 178) = ( 1 x 178 ) / 178
= 1 / 178
= 1
Step3:
LCM(1, 991) = 991
GCD(1, 991) = ( 1 x 991 ) / 991
= 1 / 991
= 1
So, Greatest Common Divisor of 842, 673, 178, 991 is 1
