Given numbers are 855, 684, 560, 450
The list of prime factors of all numbers are
Prime factors of 855 are 3 x 3 x 5 x 19
Prime factors of 684 are 2 x 2 x 3 x 3 x 19
Prime factors of 560 are 2 x 2 x 2 x 2 x 5 x 7
Prime factors of 450 are 2 x 3 x 3 x 5 x 5
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 855, 684, 560, 450
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(855, 684) = 3420
GCD(855, 684) = ( 855 x 684 ) / 3420
= 855 / 684
= 855
Step2:
LCM(171, 560) = 95760
GCD(171, 560) = ( 171 x 560 ) / 95760
= 171 / 560
= 171
Step3:
LCM(1, 450) = 450
GCD(1, 450) = ( 1 x 450 ) / 450
= 1 / 450
= 1
So, Greatest Common Divisor of 855, 684, 560, 450 is 1
