Find LCM of 462,840,220,841,815 with Prime Factorization
2 | 462, 840, 220, 841, 815 |
2 | 231, 420, 110, 841, 815 |
3 | 231, 210, 55, 841, 815 |
5 | 77, 70, 55, 841, 815 |
7 | 77, 14, 11, 841, 163 |
11 | 11, 2, 11, 841, 163 |
1, 2, 1, 841, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 11 x 1 x 2 x 1 x 841 x 163 = 1266646920
Therefore, the lowest common multiple of 462,840,220,841,815 is 1266646920.
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.
462 x 840 x 220 x 841 x 815 = 58519087704000
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.
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
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
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
841 : 1, 29, 841
815 : 1, 5, 163, 815
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 462,840,220,841,815, is 1.
Now, the common factors can be found like this.
462:2x 3x 7x 11
840:2x 2x 2x 3x 5x 7
220:2x 2x 5x 11
841:29x 29
815:5x 163
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 2x 3x 5x 5x 7x 11 = 46200
Therefore, the value for common factors is 46200.
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 = 58519087704000/(1x46200)
LCM = 58519087704000/46200
LCM = 1266646920
Thus, we can understand that the LCM of 462,840,220,841,815 is 1266646920.
