Given numbers are 371,602,642,387
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 371,602,642,387 is 30725478.
Find LCM of 371,602,642,387 with Prime Factorization
2 | 371, 602, 642, 387 |
3 | 371, 301, 321, 387 |
7 | 371, 301, 107, 129 |
43 | 53, 43, 107, 129 |
53, 1, 107, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 43 x 53 x 1 x 107 x 3 = 30725478
Therefore, the lowest common multiple of 371,602,642,387 is 30725478.
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.
371 x 602 x 642 x 387 = 55490213268
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.
371 : 1, 7, 53, 371
602 : 1, 2, 7, 14, 43, 86, 301, 602
642 : 1, 2, 3, 6, 107, 214, 321, 642
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 371,602,642,387, is 1.
Now, the common factors can be found like this.
371:7x 53
602:2x 7x 43
642:2x 3x 107
387:3x 3x 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 3x 7x 43 = 1806
Therefore, the value for common factors is 1806.
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 = 55490213268/(1x1806)
LCM = 55490213268/1806
LCM = 30725478
Thus, we can understand that the LCM of 371,602,642,387 is 30725478.
