The list of prime factors of all numbers are
Prime factors of 144 are 2 x 2 x 2 x 2 x 3 x 3
Prime factors of 140 are 2 x 2 x 5 x 7
Prime factors of 861 are 3 x 7 x 41
Prime factors of 831 are 3 x 277
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 144, 140, 861, 831
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(144, 140) = 5040
GCD(144, 140) = ( 144 x 140 ) / 5040
= 144 / 140
= 144
Step2:
LCM(4, 861) = 3444
GCD(4, 861) = ( 4 x 861 ) / 3444
= 4 / 861
= 4
Step3:
LCM(1, 831) = 831
GCD(1, 831) = ( 1 x 831 ) / 831
= 1 / 831
= 1
So, Greatest Common Divisor of 144, 140, 861, 831 is 1
