210.
The greatest common factor (or GCF) is defined as the largest number that can be divided into two (or more numbers) and result in an integer answer (no remainder).
To get the GCF, one factors the numbers involved and takes only the factors that both numbers share (the number of times that they are shared).
210 = 2 * 3 * 5 * 7
1260 = 2 * 2 * 3 * 3 * 5 * 7
Factors shared are 2, 3, 5 and 7, so 2*3*5*7 = 210.

What is the common factor for 154 and 210
What is the greatest common factor of 210 and 84?
The greatest common factor of the numbers 210 and 84 is 42.
How can I write the prime factorization and find the greatest common factor and the least common multiple of two numbers?
Example: 30 and 42 Factor them. 2 x 3 x 5 = 30 2 x 3 x 7 = 42 Select the common factors. 2 x 3 = 6, the GCF Select the highest amount of each factor. 2 x 3 x 5 x 7 = 210, the LCM Check it. 30 x 42 = 1260 6 x 210 = 1260 It checks.
How do you find LCM and HF?
Example: 30 and 42 Factor them. 2 x 3 x 5 = 30 2 x 3 x 7 = 42 Select the common factors. 2 x 3 = 6, the GCF Select the highest amount of each factor. 2 x 3 x 5 x 7 = 210, the LCM Check it. 30 x 42 = 1260 210 x 6 = 1260 It checks.
