Given numbers are 758,432,422,280,140
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 758,432,422,280,140 is 1209131280.
Find LCM of 758,432,422,280,140 with Prime Factorization
| 2 | 758, 432, 422, 280, 140 |
| 2 | 379, 216, 211, 140, 70 |
| 2 | 379, 108, 211, 35, 70 |
| 5 | 379, 54, 211, 35, 35 |
| 7 | 379, 54, 211, 7, 7 |
| 379, 54, 211, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 379 x 54 x 211 x 1 x 1 = 1209131280
Therefore, the lowest common multiple of 758,432,422,280,140 is 1209131280.
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.
758 x 432 x 422 x 280 x 140 = 5416908134400
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.
758 : 1, 2, 379, 758
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
422 : 1, 2, 211, 422
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 758,432,422,280,140, is 2.
Now, the common factors can be found like this.
758:2x 379
432:2x 2x 2x 2x 3x 3x 3
422:2x 211
280:2x 2x 2x 5x 7
140:2x 2x 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 2x 2x 5x 7 = 2240
Therefore, the value for common factors is 2240.
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 = 5416908134400/(2x2240)
LCM = 5416908134400/4480
LCM = 1209131280
Thus, we can understand that the LCM of 758,432,422,280,140 is 1209131280.
