The list of prime factors of all numbers are
Prime factors of 490 are 2 x 5 x 7 x 7
Prime factors of 122 are 2 x 61
Prime factors of 684 are 2 x 2 x 3 x 3 x 19
Prime factors of 905 are 5 x 181
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 490, 122, 684, 905
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(490, 122) = 29890
GCD(490, 122) = ( 490 x 122 ) / 29890
= 490 / 122
= 490
Step2:
LCM(2, 684) = 684
GCD(2, 684) = ( 2 x 684 ) / 684
= 2 / 684
= 2
Step3:
LCM(2, 905) = 1810
GCD(2, 905) = ( 2 x 905 ) / 1810
= 2 / 905
= 2
So, Greatest Common Divisor of 490, 122, 684, 905 is 1
