Given numbers are 142,862,701,357,240
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 142,862,701,357,240 is 612649156560.
Find LCM of 142,862,701,357,240 with Prime Factorization
| 2 | 142, 862, 701, 357, 240 |
| 3 | 71, 431, 701, 357, 120 |
| 71, 431, 701, 119, 40 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 71 x 431 x 701 x 119 x 40 = 612649156560
Therefore, the lowest common multiple of 142,862,701,357,240 is 612649156560.
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.
142 x 862 x 701 x 357 x 240 = 7351789878720
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.
142 : 1, 2, 71, 142
862 : 1, 2, 431, 862
701 : 1, 701
357 : 1, 3, 7, 17, 21, 51, 119, 357
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,862,701,357,240, is 1.
Now, the common factors can be found like this.
142:2x 71
862:2x 431
701:701
357:3x 7x 17
240:2x 2x 2x 2x 3x 5
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 3 = 12
Therefore, the value for common factors is 12.
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 = 7351789878720/(1x12)
LCM = 7351789878720/12
LCM = 612649156560
Thus, we can understand that the LCM of 142,862,701,357,240 is 612649156560.
