Find LCM of 642,736,606,119,749 with Prime Factorization
| 2 | 642, 736, 606, 119, 749 |
| 3 | 321, 368, 303, 119, 749 |
| 7 | 107, 368, 101, 119, 749 |
| 107 | 107, 368, 101, 17, 107 |
| 1, 368, 101, 17, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 107 x 1 x 368 x 101 x 17 x 1 = 2839560864
Therefore, the lowest common multiple of 642,736,606,119,749 is 2839560864.
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.
642 x 736 x 606 x 119 x 749 = 25521973045632
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
606 : 1, 2, 3, 6, 101, 202, 303, 606
119 : 1, 7, 17, 119
749 : 1, 7, 107, 749
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,736,606,119,749, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
736:2x 2x 2x 2x 2x 23
606:2x 3x 101
119:7x 17
749:7x 107
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 3x 7x 107 = 8988
Therefore, the value for common factors is 8988.
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 = 25521973045632/(1x8988)
LCM = 25521973045632/8988
LCM = 2839560864
Thus, we can understand that the LCM of 642,736,606,119,749 is 2839560864.
