The list of prime factors of all numbers are
Prime factors of 918 are 2 x 3 x 3 x 3 x 17
Prime factors of 615 are 3 x 5 x 41
Prime factors of 138 are 2 x 3 x 23
Prime factors of 166 are 2 x 83
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 918, 615, 138, 166
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(918, 615) = 188190
GCD(918, 615) = ( 918 x 615 ) / 188190
= 918 / 615
= 918
Step2:
LCM(3, 138) = 138
GCD(3, 138) = ( 3 x 138 ) / 138
= 3 / 138
= 3
Step3:
LCM(3, 166) = 498
GCD(3, 166) = ( 3 x 166 ) / 498
= 3 / 166
= 3
So, Greatest Common Divisor of 918, 615, 138, 166 is 1
