Given numbers are 894,980,640,249
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 894,980,640,249 is 1163487360.
Find LCM of 894,980,640,249 with Prime Factorization
| 2 | 894, 980, 640, 249 |
| 2 | 447, 490, 320, 249 |
| 3 | 447, 245, 160, 249 |
| 5 | 149, 245, 160, 83 |
| 149, 49, 32, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 149 x 49 x 32 x 83 = 1163487360
Therefore, the lowest common multiple of 894,980,640,249 is 1163487360.
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.
894 x 980 x 640 x 249 = 139618483200
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.
894 : 1, 2, 3, 6, 149, 298, 447, 894
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
249 : 1, 3, 83, 249
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 894,980,640,249, is 1.
Now, the common factors can be found like this.
894:2x 3x 149
980:2x 2x 5x 7x 7
640:2x 2x 2x 2x 2x 2x 2x 5
249:3x 83
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 5 = 120
Therefore, the value for common factors is 120.
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 = 139618483200/(1x120)
LCM = 139618483200/120
LCM = 1163487360
Thus, we can understand that the LCM of 894,980,640,249 is 1163487360.
