Find LCM of 749,391,570,741,510 with Prime Factorization
| 2 | 749, 391, 570, 741, 510 |
| 3 | 749, 391, 285, 741, 255 |
| 5 | 749, 391, 95, 247, 85 |
| 17 | 749, 391, 19, 247, 17 |
| 19 | 749, 23, 19, 247, 1 |
| 749, 23, 1, 13, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 19 x 749 x 23 x 1 x 13 x 1 = 2170085190
Therefore, the lowest common multiple of 749,391,570,741,510 is 2170085190.
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.
749 x 391 x 570 x 741 x 510 = 63084376473300
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.
749 : 1, 7, 107, 749
391 : 1, 17, 23, 391
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
741 : 1, 3, 13, 19, 39, 57, 247, 741
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,391,570,741,510, is 1.
Now, the common factors can be found like this.
749:7x 107
391:17x 23
570:2x 3x 5x 19
741:3x 13x 19
510:2x 3x 5x 17
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 3x 5x 17x 19 = 29070
Therefore, the value for common factors is 29070.
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 = 63084376473300/(1x29070)
LCM = 63084376473300/29070
LCM = 2170085190
Thus, we can understand that the LCM of 749,391,570,741,510 is 2170085190.
