Given numbers are 650, 354, 840, 811
The list of prime factors of all numbers are
Prime factors of 650 are 2 x 5 x 5 x 13
Prime factors of 354 are 2 x 3 x 59
Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7
Prime factors of 811 are 811
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 650, 354, 840, 811
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(650, 354) = 115050
GCD(650, 354) = ( 650 x 354 ) / 115050
= 650 / 354
= 650
Step2:
LCM(2, 840) = 840
GCD(2, 840) = ( 2 x 840 ) / 840
= 2 / 840
= 2
Step3:
LCM(2, 811) = 1622
GCD(2, 811) = ( 2 x 811 ) / 1622
= 2 / 811
= 2
So, Greatest Common Divisor of 650, 354, 840, 811 is 1
