Prime factors of 878 are 2 x 439
Prime factors of 670 are 2 x 5 x 67
Prime factors of 249 are 3 x 83
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 870, 878, 670, 249
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(870, 878) = 381930
GCD(870, 878) = ( 870 x 878 ) / 381930
= 870 / 878
= 870
Step2:
LCM(2, 670) = 670
GCD(2, 670) = ( 2 x 670 ) / 670
= 2 / 670
= 2
Step3:
LCM(2, 249) = 498
GCD(2, 249) = ( 2 x 249 ) / 498
= 2 / 249
= 2
So, Greatest Common Divisor of 870, 878, 670, 249 is 1
