Given numbers are 662,140,572,429
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 662,140,572,429 is 19879860.
Find LCM of 662,140,572,429 with Prime Factorization
2 | 662, 140, 572, 429 |
2 | 331, 70, 286, 429 |
11 | 331, 35, 143, 429 |
13 | 331, 35, 13, 39 |
331, 35, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 13 x 331 x 35 x 1 x 3 = 19879860
Therefore, the lowest common multiple of 662,140,572,429 is 19879860.
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.
662 x 140 x 572 x 429 = 22742559840
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.
662 : 1, 2, 331, 662
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
429 : 1, 3, 11, 13, 33, 39, 143, 429
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 662,140,572,429, is 1.
Now, the common factors can be found like this.
662:2x 331
140:2x 2x 5x 7
572:2x 2x 11x 13
429:3x 11x 13
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 11x 13 = 1144
Therefore, the value for common factors is 1144.
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 = 22742559840/(1x1144)
LCM = 22742559840/1144
LCM = 19879860
Thus, we can understand that the LCM of 662,140,572,429 is 19879860.
