3x19 what? microns, inches, kilometres, miles, light years?
Since 6 = 2x3, 57 = 3x19 and 99 = 3^2 x 11, the GCF is 3. This method used comparing the prime factors to determine the greatest common factor. The only common prime factor all three numbers have is 3, so it is the greatest common factor. Another, less efficient, way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 6 are 1, 2, 3, and 6. The factors of 57 are 1, 3, 19, and 57. The factors of 99 are 1, 3, 9, 11, 33, and 99. From this you can again see that the greatest common factor is 3.
3x19 what? microns, inches, kilometres, miles, light years?
57=3x19
57=3x19
57
The factor pairs of 57 are 3x19 and 1x57
It is 3. 39 is 3x1357 is 3x19.
Friendly parts? All I can say is that 57 = 3x19. 3 and 19 are prime numbers, and this is the only way to get 57 by multiplying.
The greatest, and only, common factor of 57 (=3x19) and 28 (=22x7) is 1.
- 8 - 3X = 19 (?????)add 8 to each side- 3X = 27divide both sides integers by - 3X = - 9========check in original equation- 8 - 3( - 9) = 19- 8 + 27 = 1919 = 19=======checks
0x19=0 1x19=19 2x19=38 3x19=57 4x19=76 5x19=95 6x19=114 7x19=133 8x19=152 9x19=171 I will add more tommorow but this is all for today BYE
To find out the GCF of two numbers, you first split them into their prime factors: 57 = 3x19 27 = 3x3x3 The next step is to identify any common factors. In this case, both numbers have a single 3 as a prime factor. Thus, the greatest common factor of 57 and 27 is 3.
3x14=42 3x15=45 3x16=48 3x17=51 3x18=54 3x19=57 3x20=60 3x21=63 3x22=66 3x23=69 3x24=72 3x25=75 3x26=78 3x27=81 3x28=84 3x29=87 3x30=90
