Given numbers are 670, 451, 800, 490
The list of prime factors of all numbers are
Prime factors of 670 are 2 x 5 x 67
Prime factors of 451 are 11 x 41
Prime factors of 800 are 2 x 2 x 2 x 2 x 2 x 5 x 5
Prime factors of 490 are 2 x 5 x 7 x 7
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 670, 451, 800, 490
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(670, 451) = 302170
GCD(670, 451) = ( 670 x 451 ) / 302170
= 670 / 451
= 670
Step2:
LCM(1, 800) = 800
GCD(1, 800) = ( 1 x 800 ) / 800
= 1 / 800
= 1
Step3:
LCM(1, 490) = 490
GCD(1, 490) = ( 1 x 490 ) / 490
= 1 / 490
= 1
So, Greatest Common Divisor of 670, 451, 800, 490 is 1
