The LCM of 952,542,402,840 is 259281960.
Find LCM of 952,542,402,840 with Prime Factorization
| 2 | 952, 542, 402, 840 |
| 2 | 476, 271, 201, 420 |
| 2 | 238, 271, 201, 210 |
| 3 | 119, 271, 201, 105 |
| 7 | 119, 271, 67, 35 |
| 17, 271, 67, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 17 x 271 x 67 x 5 = 259281960
Therefore, the lowest common multiple of 952,542,402,840 is 259281960.
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.
952 x 542 x 402 x 840 = 174237477120
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.
952 : 1, 2, 4, 7, 8, 14, 17, 28, 34, 56, 68, 119, 136, 238, 476, 952
542 : 1, 2, 271, 542
402 : 1, 2, 3, 6, 67, 134, 201, 402
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
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 952,542,402,840, is 2.
Now, the common factors can be found like this.
952:2x 2x 2x 7x 17
542:2x 271
402:2x 3x 67
840:2x 2x 2x 3x 5x 7
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 2x 3x 7 = 336
Therefore, the value for common factors is 336.
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 = 174237477120/(2x336)
LCM = 174237477120/672
LCM = 259281960
Thus, we can understand that the LCM of 952,542,402,840 is 259281960.
