Given numbers are 120, 720, 708, 845
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 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5
Prime factors of 708 are 2 x 2 x 3 x 59
Prime factors of 845 are 5 x 13 x 13
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 120, 720, 708, 845
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(120, 720) = 720
GCD(120, 720) = ( 120 x 720 ) / 720
= 120 / 720
= 120
Step2:
LCM(120, 708) = 7080
GCD(120, 708) = ( 120 x 708 ) / 7080
= 120 / 708
= 120
Step3:
LCM(12, 845) = 10140
GCD(12, 845) = ( 12 x 845 ) / 10140
= 12 / 845
= 12
So, Greatest Common Divisor of 120, 720, 708, 845 is 1
