Prime factors of 468 are 2 x 2 x 3 x 3 x 13
Prime factors of 398 are 2 x 199
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 155, 520, 468, 398
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(155, 520) = 16120
GCD(155, 520) = ( 155 x 520 ) / 16120
= 155 / 520
= 155
Step2:
LCM(5, 468) = 2340
GCD(5, 468) = ( 5 x 468 ) / 2340
= 5 / 468
= 5
Step3:
LCM(1, 398) = 398
GCD(1, 398) = ( 1 x 398 ) / 398
= 1 / 398
= 1
So, Greatest Common Divisor of 155, 520, 468, 398 is 1
