Given numbers are 310, 492, 620, 145
The list of prime factors of all numbers are
Prime factors of 310 are 2 x 5 x 31
Prime factors of 492 are 2 x 2 x 3 x 41
Prime factors of 620 are 2 x 2 x 5 x 31
Prime factors of 145 are 5 x 29
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 310, 492, 620, 145
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(310, 492) = 76260
GCD(310, 492) = ( 310 x 492 ) / 76260
= 310 / 492
= 310
Step2:
LCM(2, 620) = 620
GCD(2, 620) = ( 2 x 620 ) / 620
= 2 / 620
= 2
Step3:
LCM(2, 145) = 290
GCD(2, 145) = ( 2 x 145 ) / 290
= 2 / 145
= 2
So, Greatest Common Divisor of 310, 492, 620, 145 is 1
