Given numbers are 429,636,722,931
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 429,636,722,931 is 1608779172.
Find LCM of 429,636,722,931 with Prime Factorization
| 2 | 429, 636, 722, 931 |
| 3 | 429, 318, 361, 931 |
| 19 | 143, 106, 361, 931 |
| 143, 106, 19, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 143 x 106 x 19 x 49 = 1608779172
Therefore, the lowest common multiple of 429,636,722,931 is 1608779172.
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.
429 x 636 x 722 x 931 = 183400825608
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.
429 : 1, 3, 11, 13, 33, 39, 143, 429
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
722 : 1, 2, 19, 38, 361, 722
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 429,636,722,931, is 1.
Now, the common factors can be found like this.
429:3x 11x 13
636:2x 2x 3x 53
722:2x 19x 19
931:7x 7x 19
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 19 = 114
Therefore, the value for common factors is 114.
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 = 183400825608/(1x114)
LCM = 183400825608/114
LCM = 1608779172
Thus, we can understand that the LCM of 429,636,722,931 is 1608779172.
