Find LCM of 700,650,579,520,391 with Prime Factorization
| 2 | 700, 650, 579, 520, 391 |
| 2 | 350, 325, 579, 260, 391 |
| 5 | 175, 325, 579, 130, 391 |
| 5 | 35, 65, 579, 26, 391 |
| 13 | 7, 13, 579, 26, 391 |
| 7, 1, 579, 2, 391 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 5 x 13 x 7 x 1 x 579 x 2 x 391 = 4120279800
Therefore, the lowest common multiple of 700,650,579,520,391 is 4120279800.
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.
700 x 650 x 579 x 520 x 391 = 53563637400000
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.
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
579 : 1, 3, 193, 579
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 700,650,579,520,391, is 1.
Now, the common factors can be found like this.
700:2x 2x 5x 5x 7
650:2x 5x 5x 13
579:3x 193
520:2x 2x 2x 5x 13
391:17x 23
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 5x 5x 5x 13 = 13000
Therefore, the value for common factors is 13000.
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 = 53563637400000/(1x13000)
LCM = 53563637400000/13000
LCM = 4120279800
Thus, we can understand that the LCM of 700,650,579,520,391 is 4120279800.
