Find LCM of 278,709,175,840,663 with Prime Factorization
| 2 | 278, 709, 175, 840, 663 |
| 3 | 139, 709, 175, 420, 663 |
| 5 | 139, 709, 175, 140, 221 |
| 7 | 139, 709, 35, 28, 221 |
| 139, 709, 5, 4, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 139 x 709 x 5 x 4 x 221 = 91475038200
Therefore, the lowest common multiple of 278,709,175,840,663 is 91475038200.
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.
278 x 709 x 175 x 840 x 663 = 19209758022000
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.
278 : 1, 2, 139, 278
709 : 1, 709
175 : 1, 5, 7, 25, 35, 175
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,709,175,840,663, is 1.
Now, the common factors can be found like this.
278:2x 139
709:709
175:5x 5x 7
840:2x 2x 2x 3x 5x 7
663:3x 13x 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 5x 7 = 210
Therefore, the value for common factors is 210.
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 = 19209758022000/(1x210)
LCM = 19209758022000/210
LCM = 91475038200
Thus, we can understand that the LCM of 278,709,175,840,663 is 91475038200.
