Given numbers are 624, 665, 155, 857
The list of prime factors of all numbers are
Prime factors of 624 are 2 x 2 x 2 x 2 x 3 x 13
Prime factors of 665 are 5 x 7 x 19
Prime factors of 155 are 5 x 31
Prime factors of 857 are 857
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 624, 665, 155, 857
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(624, 665) = 414960
GCD(624, 665) = ( 624 x 665 ) / 414960
= 624 / 665
= 624
Step2:
LCM(1, 155) = 155
GCD(1, 155) = ( 1 x 155 ) / 155
= 1 / 155
= 1
Step3:
LCM(1, 857) = 857
GCD(1, 857) = ( 1 x 857 ) / 857
= 1 / 857
= 1
So, Greatest Common Divisor of 624, 665, 155, 857 is 1
