Prime factors of 155 are 5 x 31
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 358, 641, 340, 155
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(358, 641) = 229478
GCD(358, 641) = ( 358 x 641 ) / 229478
= 358 / 641
= 358
Step2:
LCM(1, 340) = 340
GCD(1, 340) = ( 1 x 340 ) / 340
= 1 / 340
= 1
Step3:
LCM(1, 155) = 155
GCD(1, 155) = ( 1 x 155 ) / 155
= 1 / 155
= 1
So, Greatest Common Divisor of 358, 641, 340, 155 is 1
