Given numbers are 90, 99, 62, 12
The list of prime factors of all numbers are
Prime factors of 90 are 2 x 3 x 3 x 5
Prime factors of 99 are 3 x 3 x 11
Prime factors of 62 are 2 x 31
Prime factors of 12 are 2 x 2 x 3
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 90, 99, 62, 12
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(90, 99) = 990
GCD(90, 99) = ( 90 x 99 ) / 990
= 90 / 99
= 90
Step2:
LCM(9, 62) = 558
GCD(9, 62) = ( 9 x 62 ) / 558
= 9 / 62
= 9
Step3:
LCM(1, 12) = 12
GCD(1, 12) = ( 1 x 12 ) / 12
= 1 / 12
= 1
So, Greatest Common Divisor of 90, 99, 62, 12 is 1
