Prime factors of 515 are 5 x 103
Prime factors of 430 are 2 x 5 x 43
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 887, 515, 430, 840
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(887, 515) = 456805
GCD(887, 515) = ( 887 x 515 ) / 456805
= 887 / 515
= 887
Step2:
LCM(1, 430) = 430
GCD(1, 430) = ( 1 x 430 ) / 430
= 1 / 430
= 1
Step3:
LCM(1, 840) = 840
GCD(1, 840) = ( 1 x 840 ) / 840
= 1 / 840
= 1
So, Greatest Common Divisor of 887, 515, 430, 840 is 1
