The LCM of 287,154,479,835,770 is 2525379010.
Find LCM of 287,154,479,835,770 with Prime Factorization
| 2 | 287, 154, 479, 835, 770 |
| 5 | 287, 77, 479, 835, 385 |
| 7 | 287, 77, 479, 167, 77 |
| 11 | 41, 11, 479, 167, 11 |
| 41, 1, 479, 167, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 41 x 1 x 479 x 167 x 1 = 2525379010
Therefore, the lowest common multiple of 287,154,479,835,770 is 2525379010.
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.
287 x 154 x 479 x 835 x 770 = 13611792863900
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.
287 : 1, 7, 41, 287
154 : 1, 2, 7, 11, 14, 22, 77, 154
479 : 1, 479
835 : 1, 5, 167, 835
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,154,479,835,770, is 1.
Now, the common factors can be found like this.
287:7x 41
154:2x 7x 11
479:479
835:5x 167
770:2x 5x 7x 11
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 7x 7x 11 = 5390
Therefore, the value for common factors is 5390.
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 = 13611792863900/(1x5390)
LCM = 13611792863900/5390
LCM = 2525379010
Thus, we can understand that the LCM of 287,154,479,835,770 is 2525379010.
