Given numbers are 845, 660, 840, 291
The list of prime factors of all numbers are
Prime factors of 845 are 5 x 13 x 13
Prime factors of 660 are 2 x 2 x 3 x 5 x 11
Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7
Prime factors of 291 are 3 x 97
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 845, 660, 840, 291
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(845, 660) = 111540
GCD(845, 660) = ( 845 x 660 ) / 111540
= 845 / 660
= 845
Step2:
LCM(5, 840) = 840
GCD(5, 840) = ( 5 x 840 ) / 840
= 5 / 840
= 5
Step3:
LCM(5, 291) = 1455
GCD(5, 291) = ( 5 x 291 ) / 1455
= 5 / 291
= 5
So, Greatest Common Divisor of 845, 660, 840, 291 is 1
