Find LCM of 681,581,570,113,490 with Prime Factorization
| 2 | 681, 581, 570, 113, 490 |
| 3 | 681, 581, 285, 113, 245 |
| 5 | 227, 581, 95, 113, 245 |
| 7 | 227, 581, 19, 113, 49 |
| 227, 83, 19, 113, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 227 x 83 x 19 x 113 x 7 = 59463891690
Therefore, the lowest common multiple of 681,581,570,113,490 is 59463891690.
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.
681 x 581 x 570 x 113 x 490 = 12487417254900
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.
681 : 1, 3, 227, 681
581 : 1, 7, 83, 581
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
113 : 1, 113
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,581,570,113,490, is 1.
Now, the common factors can be found like this.
681:3x 227
581:7x 83
570:2x 3x 5x 19
113:113
490:2x 5x 7x 7
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 = 12487417254900/(1x210)
LCM = 12487417254900/210
LCM = 59463891690
Thus, we can understand that the LCM of 681,581,570,113,490 is 59463891690.
