Given numbers are 840, 903, 408, 680
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 903 are 3 x 7 x 43
Prime factors of 408 are 2 x 2 x 2 x 3 x 17
Prime factors of 680 are 2 x 2 x 2 x 5 x 17
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 840, 903, 408, 680
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 903) = 36120
GCD(840, 903) = ( 840 x 903 ) / 36120
= 840 / 903
= 840
Step2:
LCM(21, 408) = 2856
GCD(21, 408) = ( 21 x 408 ) / 2856
= 21 / 408
= 21
Step3:
LCM(3, 680) = 2040
GCD(3, 680) = ( 3 x 680 ) / 2040
= 3 / 680
= 3
So, Greatest Common Divisor of 840, 903, 408, 680 is 1
