Find LCM of 715,821,510,312 with Prime Factorization
| 2 | 715, 821, 510, 312 |
| 3 | 715, 821, 255, 156 |
| 5 | 715, 821, 85, 52 |
| 13 | 143, 821, 17, 52 |
| 11, 821, 17, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 11 x 821 x 17 x 4 = 239502120
Therefore, the lowest common multiple of 715,821,510,312 is 239502120.
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.
715 x 821 x 510 x 312 = 93405826800
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.
715 : 1, 5, 11, 13, 55, 65, 143, 715
821 : 1, 821
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,821,510,312, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
821:821
510:2x 3x 5x 17
312:2x 2x 2x 3x 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 3x 5x 13 = 390
Therefore, the value for common factors is 390.
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 = 93405826800/(1x390)
LCM = 93405826800/390
LCM = 239502120
Thus, we can understand that the LCM of 715,821,510,312 is 239502120.
