The list of prime factors of all numbers are
Prime factors of 161 are 7 x 23
Prime factors of 858 are 2 x 3 x 11 x 13
Prime factors of 615 are 3 x 5 x 41
Prime factors of 100 are 2 x 2 x 5 x 5
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 161, 858, 615, 100
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(161, 858) = 138138
GCD(161, 858) = ( 161 x 858 ) / 138138
= 161 / 858
= 161
Step2:
LCM(1, 615) = 615
GCD(1, 615) = ( 1 x 615 ) / 615
= 1 / 615
= 1
Step3:
LCM(1, 100) = 100
GCD(1, 100) = ( 1 x 100 ) / 100
= 1 / 100
= 1
So, Greatest Common Divisor of 161, 858, 615, 100 is 1
