The list of prime factors of all numbers are
Prime factors of 108 are 2 x 2 x 3 x 3 x 3
Prime factors of 153 are 3 x 3 x 17
Prime factors of 780 are 2 x 2 x 3 x 5 x 13
Prime factors of 445 are 5 x 89
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 108, 153, 780, 445
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(108, 153) = 1836
GCD(108, 153) = ( 108 x 153 ) / 1836
= 108 / 153
= 108
Step2:
LCM(9, 780) = 2340
GCD(9, 780) = ( 9 x 780 ) / 2340
= 9 / 780
= 9
Step3:
LCM(3, 445) = 1335
GCD(3, 445) = ( 3 x 445 ) / 1335
= 3 / 445
= 3
So, Greatest Common Divisor of 108, 153, 780, 445 is 1
