Find LCM of 369,312,642,510,728 with Prime Factorization
2 | 369, 312, 642, 510, 728 |
2 | 369, 156, 321, 255, 364 |
2 | 369, 78, 321, 255, 182 |
3 | 369, 39, 321, 255, 91 |
13 | 123, 13, 107, 85, 91 |
123, 1, 107, 85, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 13 x 123 x 1 x 107 x 85 x 7 = 2443208040
Therefore, the lowest common multiple of 369,312,642,510,728 is 2443208040.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
369 x 312 x 642 x 510 x 728 = 27442112705280
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
369 : 1, 3, 9, 41, 123, 369
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
642 : 1, 2, 3, 6, 107, 214, 321, 642
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 369,312,642,510,728, is 1.
Now, the common factors can be found like this.
369:3x 3x 41
312:2x 2x 2x 3x 13
642:2x 3x 107
510:2x 3x 5x 17
728:2x 2x 2x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2x 3x 3x 3x 13 = 11232
Therefore, the value for common factors is 11232.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 27442112705280/(1x11232)
LCM = 27442112705280/11232
LCM = 2443208040
Thus, we can understand that the LCM of 369,312,642,510,728 is 2443208040.
