1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315.
Since 315 is a factor of 3150, all of its factors are common.
315 has factors 3,3.5,7. 356 has factors of 2,2,89. There are no common factors between these two numbers , except '1'.
1,3,5,15 and 45
LCM of 21 and 45=315 Factors of 21= 3x7 Factors of 45=3x3x5 Lcm= 3x5x7x3=315
The GCF is 5.
Since 315 is a factor of 3150, it is automatically the GCF.
The first step is to express these numbers as products of their prime factors: 315 = 3x3x5x7 660 = 2x2x3x5x11 The next step is to identify any common prime factors. In this case the common prime factors are 3 and 5. Multiply these and you get: 3x5 = 15 Thus the HCF of 315 and 660 is 15.
To find the greater common factor (GCF) of two ( or more) numbers, factorise each number. Hence 126 has factors of 2,3,3,7 315 has factors of 3,3,5,7 The common factors are '3' , '3' again and '7'. Multiply together 3 x 3 x 7 = 9 x 7 = 63 The GCF of 126, & 315. NB The '2' & '5' are NOT common to both numbers.
The GCF of 60 and 315 is 15.The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60The factors of 315 are: 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315The common factors are: 1, 3, 5, 15The Greatest Common Factor (GCF) is: 15
The only number that will divide equally into both 256 and 315 is the number 1. There are no common factors of the two numbers greater than this.
3 x 3 x 5 x 7 = 315 The prime factors of 315 are 3, 5, and 7.
The prime factors of 315 are 3, 3, 5, and 7.
