Given numbers are 170, 655, 448, 154
The list of prime factors of all numbers are
Prime factors of 170 are 2 x 5 x 17
Prime factors of 655 are 5 x 131
Prime factors of 448 are 2 x 2 x 2 x 2 x 2 x 2 x 7
Prime factors of 154 are 2 x 7 x 11
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 170, 655, 448, 154
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(170, 655) = 22270
GCD(170, 655) = ( 170 x 655 ) / 22270
= 170 / 655
= 170
Step2:
LCM(5, 448) = 2240
GCD(5, 448) = ( 5 x 448 ) / 2240
= 5 / 448
= 5
Step3:
LCM(1, 154) = 154
GCD(1, 154) = ( 1 x 154 ) / 154
= 1 / 154
= 1
So, Greatest Common Divisor of 170, 655, 448, 154 is 1
