Given numbers are 100, 720, 158, 915
The list of prime factors of all numbers are
Prime factors of 100 are 2 x 2 x 5 x 5
Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5
Prime factors of 158 are 2 x 79
Prime factors of 915 are 3 x 5 x 61
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 100, 720, 158, 915
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(100, 720) = 3600
GCD(100, 720) = ( 100 x 720 ) / 3600
= 100 / 720
= 100
Step2:
LCM(20, 158) = 1580
GCD(20, 158) = ( 20 x 158 ) / 1580
= 20 / 158
= 20
Step3:
LCM(2, 915) = 1830
GCD(2, 915) = ( 2 x 915 ) / 1830
= 2 / 915
= 2
So, Greatest Common Divisor of 100, 720, 158, 915 is 1
