Given numbers are 120, 705, 620, 481
The list of prime factors of all numbers are
Prime factors of 120 are 2 x 2 x 2 x 3 x 5
Prime factors of 705 are 3 x 5 x 47
Prime factors of 620 are 2 x 2 x 5 x 31
Prime factors of 481 are 13 x 37
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 120, 705, 620, 481
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(120, 705) = 5640
GCD(120, 705) = ( 120 x 705 ) / 5640
= 120 / 705
= 120
Step2:
LCM(15, 620) = 1860
GCD(15, 620) = ( 15 x 620 ) / 1860
= 15 / 620
= 15
Step3:
LCM(5, 481) = 2405
GCD(5, 481) = ( 5 x 481 ) / 2405
= 5 / 481
= 5
So, Greatest Common Divisor of 120, 705, 620, 481 is 1
