Given numbers are 870, 100, 705, 709
The list of prime factors of all numbers are
Prime factors of 870 are 2 x 3 x 5 x 29
Prime factors of 100 are 2 x 2 x 5 x 5
Prime factors of 705 are 3 x 5 x 47
Prime factors of 709 are 709
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 870, 100, 705, 709
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(870, 100) = 8700
GCD(870, 100) = ( 870 x 100 ) / 8700
= 870 / 100
= 870
Step2:
LCM(10, 705) = 1410
GCD(10, 705) = ( 10 x 705 ) / 1410
= 10 / 705
= 10
Step3:
LCM(5, 709) = 3545
GCD(5, 709) = ( 5 x 709 ) / 3545
= 5 / 709
= 5
So, Greatest Common Divisor of 870, 100, 705, 709 is 1
