Find LCM of 907,686,490,179,820 with Prime Factorization
| 2 | 907, 686, 490, 179, 820 |
| 5 | 907, 343, 245, 179, 410 |
| 7 | 907, 343, 49, 179, 82 |
| 7 | 907, 7, 49, 179, 82 |
| 907, 1, 7, 179, 82 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 7 x 907 x 1 x 7 x 179 x 82 = 45663404780
Therefore, the lowest common multiple of 907,686,490,179,820 is 45663404780.
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.
907 x 686 x 490 x 179 x 820 = 44750136684400
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.
907 : 1, 907
686 : 1, 2, 7, 14, 49, 98, 343, 686
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
179 : 1, 179
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 907,686,490,179,820, is 1.
Now, the common factors can be found like this.
907:907
686:2x 7x 7x 7
490:2x 5x 7x 7
179:179
820:2x 2x 5x 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 5x 7x 7 = 980
Therefore, the value for common factors is 980.
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 = 44750136684400/(1x980)
LCM = 44750136684400/980
LCM = 45663404780
Thus, we can understand that the LCM of 907,686,490,179,820 is 45663404780.
