Given numbers are 843, 130, 844, 215
The list of prime factors of all numbers are
Prime factors of 843 are 3 x 281
Prime factors of 130 are 2 x 5 x 13
Prime factors of 844 are 2 x 2 x 211
Prime factors of 215 are 5 x 43
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 843, 130, 844, 215
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(843, 130) = 109590
GCD(843, 130) = ( 843 x 130 ) / 109590
= 843 / 130
= 843
Step2:
LCM(1, 844) = 844
GCD(1, 844) = ( 1 x 844 ) / 844
= 1 / 844
= 1
Step3:
LCM(1, 215) = 215
GCD(1, 215) = ( 1 x 215 ) / 215
= 1 / 215
= 1
So, Greatest Common Divisor of 843, 130, 844, 215 is 1
