Find LCM of 468,820,695,665,738 with Prime Factorization
| 2 | 468, 820, 695, 665, 738 |
| 2 | 234, 410, 695, 665, 369 |
| 3 | 117, 205, 695, 665, 369 |
| 3 | 39, 205, 695, 665, 123 |
| 5 | 13, 205, 695, 665, 41 |
| 41 | 13, 41, 139, 133, 41 |
| 13, 1, 139, 133, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 41 x 13 x 1 x 139 x 133 x 1 = 1773642780
Therefore, the lowest common multiple of 468,820,695,665,738 is 1773642780.
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.
468 x 820 x 695 x 665 x 738 = 130894837164000
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.
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
695 : 1, 5, 139, 695
665 : 1, 5, 7, 19, 35, 95, 133, 665
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 468,820,695,665,738, is 1.
Now, the common factors can be found like this.
468:2x 2x 3x 3x 13
820:2x 2x 5x 41
695:5x 139
665:5x 7x 19
738:2x 3x 3x 41
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 3x 3x 5x 5x 41 = 73800
Therefore, the value for common factors is 73800.
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 = 130894837164000/(1x73800)
LCM = 130894837164000/73800
LCM = 1773642780
Thus, we can understand that the LCM of 468,820,695,665,738 is 1773642780.
