To find the greatest common factor of two or more numbers, first find the factors of each number,
270 - 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
345 - 1, 3, 5, 15, 23. 60. 115. 345
The largest factor they both share is the GCF.
The GCF of 270 and 345 is 15.
The GCF is 15.
270
The GCF is 1.
The GCF of 345, 253 and 115 is 23.
The GCF is 54.
gcf for these numbers 345 253 and 115 is 23.
The GCF of 72, 270 and 810 is: 18
You need at least two numbers to find a GCF. IF that's 3, 4 and 5, the GCF of consecutive nonzero integers is 1.
The GCF of 270 and 360 is 90.
The GCF is 18.
The GCF of 153 and 270 is 3 * 3 = 9
Since 45 is a factor of 270, it is automatically the GCF.
