Given numbers are 635, 667, 648, 840
The list of prime factors of all numbers are
Prime factors of 635 are 5 x 127
Prime factors of 667 are 23 x 29
Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3
Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 635, 667, 648, 840
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(635, 667) = 423545
GCD(635, 667) = ( 635 x 667 ) / 423545
= 635 / 667
= 635
Step2:
LCM(1, 648) = 648
GCD(1, 648) = ( 1 x 648 ) / 648
= 1 / 648
= 1
Step3:
LCM(1, 840) = 840
GCD(1, 840) = ( 1 x 840 ) / 840
= 1 / 840
= 1
So, Greatest Common Divisor of 635, 667, 648, 840 is 1
