Find LCM of 220,861,618,817,154 with Prime Factorization
| 2 | 220, 861, 618, 817, 154 |
| 3 | 110, 861, 309, 817, 77 |
| 7 | 110, 287, 103, 817, 77 |
| 11 | 110, 41, 103, 817, 11 |
| 10, 41, 103, 817, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 10 x 41 x 103 x 817 x 1 = 15939882420
Therefore, the lowest common multiple of 220,861,618,817,154 is 15939882420.
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.
220 x 861 x 618 x 817 x 154 = 14728451356080
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
861 : 1, 3, 7, 21, 41, 123, 287, 861
618 : 1, 2, 3, 6, 103, 206, 309, 618
817 : 1, 19, 43, 817
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,861,618,817,154, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
861:3x 7x 41
618:2x 3x 103
817:19x 43
154:2x 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 2x 3x 7x 11 = 924
Therefore, the value for common factors is 924.
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 = 14728451356080/(1x924)
LCM = 14728451356080/924
LCM = 15939882420
Thus, we can understand that the LCM of 220,861,618,817,154 is 15939882420.
