What is the greatest common factor in 2 and 7?
The greatest common factor would be 14 because 7 times 2 = 14 and 2x7=14 The GCF= 14
What is the greatest common factor for 4 and 22?
the greatest common factor for 4 and 22 is 2 because 2 times 2 is 4 and 11 times 2 is 22 .
What is the greatest common factor of 63 81 and 18?
well 18: 2 times 3 times 3 and 63: 3 times 3 times 7 and 117:3 times 3 times 13 the number tat ocurs the most is :3 and 3 so u multiply 3 times 3 = 9 so the GCD IS 9! hope this helps and byee done by: Paven Samrai
Greatest common factor of 42 and 70?
14....it goes into 42 three times and into 70 five times.
What is the greatest common factor of 91 and 42?
First Number: 52Second Number: 91Third Number: 104The Greatest Common Factor (GCF) is: 13Example Simplified Fraction: 52/91 => 4/7 (4 times 13 =52; 7 times 13=91; 104 divided by 13=8)The Greatest Common Factor of 30, 75, 90 = 15Example Simplified Fraction: 30/75 => 2/5The Greatest Common Factor (GCF) is 2 for 118 and 116.Example Simplified Fraction: 118/116 => 59/58It is a common factor if it is a factor of two or more numbers - it is then "common to" those numbers. Example: for 12 and 30, the factors for 12 are 1, 2, 3, 4, 6 and 12.The factors of 30 are 1, 2, 3, 5, 6, 10, 15 and 301,2,3 and 6 appear in both lists. So, the common factors of 12 and 30 are: 1, 2, 3 and 6. The "Greatest Common Factor" is merely the largest of the common factors (so 6 would be the greatest common factor for 12 and 30).Finding the Greatest Common Factor:Choose 2 numbers (ex. 9 and 18).9's factors: 9: 1,3,918's factors: 1,2,3,6,9,181, 3, 9 are common; 9 is the greatest common factor.Using the GCF Tool, the greatest number of identical snacks from the numbers 63 and 105 is 21 (Example Simplified Fraction: 63/105 => 3/5): 21 times 3= 63; 21 times 5=105.so the gcf is 13
