Given numbers are 181, 642, 668, 886
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(181, 642) = 116202
GCD(181, 642) = ( 181 x 642 ) / 116202
= 181 / 642
= 181
Step2:
LCM(1, 668) = 668
GCD(1, 668) = ( 1 x 668 ) / 668
= 1 / 668
= 1
Step3:
LCM(1, 886) = 886
GCD(1, 886) = ( 1 x 886 ) / 886
= 1 / 886
= 1
So, Greatest Common Divisor of 181, 642, 668, 886 is 1
