Given numbers are 972, 530, 905, 806
The list of prime factors of all numbers are
Prime factors of 972 are 2 x 2 x 3 x 3 x 3 x 3 x 3
Prime factors of 530 are 2 x 5 x 53
Prime factors of 905 are 5 x 181
Prime factors of 806 are 2 x 13 x 31
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 972, 530, 905, 806
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(972, 530) = 257580
GCD(972, 530) = ( 972 x 530 ) / 257580
= 972 / 530
= 972
Step2:
LCM(2, 905) = 1810
GCD(2, 905) = ( 2 x 905 ) / 1810
= 2 / 905
= 2
Step3:
LCM(1, 806) = 806
GCD(1, 806) = ( 1 x 806 ) / 806
= 1 / 806
= 1
So, Greatest Common Divisor of 972, 530, 905, 806 is 1
