Find LCM of 490,167,759,748,391 with Prime Factorization
2 | 490, 167, 759, 748, 391 |
11 | 245, 167, 759, 374, 391 |
17 | 245, 167, 69, 34, 391 |
23 | 245, 167, 69, 2, 23 |
245, 167, 3, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 17 x 23 x 245 x 167 x 3 x 2 x 1 = 2111704980
Therefore, the lowest common multiple of 490,167,759,748,391 is 2111704980.
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.
490 x 167 x 759 x 748 x 391 = 18164886237960
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.
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
167 : 1, 167
759 : 1, 3, 11, 23, 33, 69, 253, 759
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 490,167,759,748,391, is 1.
Now, the common factors can be found like this.
490:2x 5x 7x 7
167:167
759:3x 11x 23
748:2x 2x 11x 17
391:17x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 17x 23 = 8602
Therefore, the value for common factors is 8602.
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 = 18164886237960/(1x8602)
LCM = 18164886237960/8602
LCM = 2111704980
Thus, we can understand that the LCM of 490,167,759,748,391 is 2111704980.
