Given numbers are 675,689,814,455,628
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 675,689,814,455,628 is 832099167900.
Find LCM of 675,689,814,455,628 with Prime Factorization
| 2 | 675, 689, 814, 455, 628 |
| 5 | 675, 689, 407, 455, 314 |
| 13 | 135, 689, 407, 91, 314 |
| 135, 53, 407, 7, 314 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 135 x 53 x 407 x 7 x 314 = 832099167900
Therefore, the lowest common multiple of 675,689,814,455,628 is 832099167900.
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.
675 x 689 x 814 x 455 x 628 = 108172891827000
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.
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
689 : 1, 13, 53, 689
814 : 1, 2, 11, 22, 37, 74, 407, 814
455 : 1, 5, 7, 13, 35, 65, 91, 455
628 : 1, 2, 4, 157, 314, 628
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 675,689,814,455,628, is 1.
Now, the common factors can be found like this.
675:3x 3x 3x 5x 5
689:13x 53
814:2x 11x 37
455:5x 7x 13
628:2x 2x 157
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 13 = 130
Therefore, the value for common factors is 130.
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 = 108172891827000/(1x130)
LCM = 108172891827000/130
LCM = 832099167900
Thus, we can understand that the LCM of 675,689,814,455,628 is 832099167900.
