Find LCM of 870,320,249,457,919 with Prime Factorization
| 2 | 870, 320, 249, 457, 919 |
| 3 | 435, 160, 249, 457, 919 |
| 5 | 145, 160, 83, 457, 919 |
| 29, 32, 83, 457, 919 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 29 x 32 x 83 x 457 x 919 = 970463117760
Therefore, the lowest common multiple of 870,320,249,457,919 is 970463117760.
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.
870 x 320 x 249 x 457 x 919 = 29113893532800
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.
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
249 : 1, 3, 83, 249
457 : 1, 457
919 : 1, 919
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 870,320,249,457,919, is 1.
Now, the common factors can be found like this.
870:2x 3x 5x 29
320:2x 2x 2x 2x 2x 2x 5
249:3x 83
457:457
919:919
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 5 = 30
Therefore, the value for common factors is 30.
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 = 29113893532800/(1x30)
LCM = 29113893532800/30
LCM = 970463117760
Thus, we can understand that the LCM of 870,320,249,457,919 is 970463117760.
