The GCF of 24 and 90 is 6. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. The factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90. The common factors are 1, 2, 3, and 6, so the greatest common factor is 6. You can also determine the greatest common factor using the prime factors.
First of all find the greatest common divisor of 24 and 45, then the greatest common divisor of that result and 90 will be your answer:
[tex]GCD(24,45)=8[/tex]
[tex]GCD(8, 90)=2[/tex]
[tex]GCD(24, 45, 90)=2[/tex]
So, the greatest common divisor of 24, 45 and 90 is 2.
[tex]GCD(24,45)=8[/tex]
[tex]GCD(8, 90)=2[/tex]
[tex]GCD(24, 45, 90)=2[/tex]
So, the greatest common divisor of 24, 45 and 90 is 2.
