Given numbers are 126,875,638,430
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 126,875,638,430 is 216042750.
Find LCM of 126,875,638,430 with Prime Factorization
| 2 | 126, 875, 638, 430 |
| 5 | 63, 875, 319, 215 |
| 7 | 63, 175, 319, 43 |
| 9, 25, 319, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 9 x 25 x 319 x 43 = 216042750
Therefore, the lowest common multiple of 126,875,638,430 is 216042750.
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.
126 x 875 x 638 x 430 = 30245985000
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.
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
875 : 1, 5, 7, 25, 35, 125, 175, 875
638 : 1, 2, 11, 22, 29, 58, 319, 638
430 : 1, 2, 5, 10, 43, 86, 215, 430
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 126,875,638,430, is 1.
Now, the common factors can be found like this.
126:2x 3x 3x 7
875:5x 5x 5x 7
638:2x 11x 29
430:2x 5x 43
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 7 = 140
Therefore, the value for common factors is 140.
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 = 30245985000/(1x140)
LCM = 30245985000/140
LCM = 216042750
Thus, we can understand that the LCM of 126,875,638,430 is 216042750.
