The LCM of 220,689,295,944 is 35772880.
Find LCM of 220,689,295,944 with Prime Factorization
| 2 | 220, 689, 295, 944 |
| 2 | 110, 689, 295, 472 |
| 5 | 55, 689, 295, 236 |
| 59 | 11, 689, 59, 236 |
| 11, 689, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 59 x 11 x 689 x 1 x 4 = 35772880
Therefore, the lowest common multiple of 220,689,295,944 is 35772880.
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 689 x 295 x 944 = 42211998400
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
689 : 1, 13, 53, 689
295 : 1, 5, 59, 295
944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,689,295,944, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
689:13x 53
295:5x 59
944:2x 2x 2x 2x 59
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 5x 59 = 1180
Therefore, the value for common factors is 1180.
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 = 42211998400/(1x1180)
LCM = 42211998400/1180
LCM = 35772880
Thus, we can understand that the LCM of 220,689,295,944 is 35772880.
