Given numbers are 420, 700, 587, 985
The list of prime factors of all numbers are
Prime factors of 420 are 2 x 2 x 3 x 5 x 7
Prime factors of 700 are 2 x 2 x 5 x 5 x 7
Prime factors of 587 are 587
Prime factors of 985 are 5 x 197
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 420, 700, 587, 985
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 700) = 2100
GCD(420, 700) = ( 420 x 700 ) / 2100
= 420 / 700
= 420
Step2:
LCM(140, 587) = 82180
GCD(140, 587) = ( 140 x 587 ) / 82180
= 140 / 587
= 140
Step3:
LCM(1, 985) = 985
GCD(1, 985) = ( 1 x 985 ) / 985
= 1 / 985
= 1
So, Greatest Common Divisor of 420, 700, 587, 985 is 1
