Given numbers are 840, 220, 801, 818
The list of prime factors of all numbers are
Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7
Prime factors of 220 are 2 x 2 x 5 x 11
Prime factors of 801 are 3 x 3 x 89
Prime factors of 818 are 2 x 409
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 840, 220, 801, 818
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 220) = 9240
GCD(840, 220) = ( 840 x 220 ) / 9240
= 840 / 220
= 840
Step2:
LCM(20, 801) = 16020
GCD(20, 801) = ( 20 x 801 ) / 16020
= 20 / 801
= 20
Step3:
LCM(1, 818) = 818
GCD(1, 818) = ( 1 x 818 ) / 818
= 1 / 818
= 1
So, Greatest Common Divisor of 840, 220, 801, 818 is 1
