Given numbers are 693,572,429,815
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 693,572,429,815 is 29369340.
Find LCM of 693,572,429,815 with Prime Factorization
3 | 693, 572, 429, 815 |
11 | 231, 572, 143, 815 |
13 | 21, 52, 13, 815 |
21, 4, 1, 815 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 13 x 21 x 4 x 1 x 815 = 29369340
Therefore, the lowest common multiple of 693,572,429,815 is 29369340.
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.
693 x 572 x 429 x 815 = 138593915460
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.
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
429 : 1, 3, 11, 13, 33, 39, 143, 429
815 : 1, 5, 163, 815
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 693,572,429,815, is 1.
Now, the common factors can be found like this.
693:3x 3x 7x 11
572:2x 2x 11x 13
429:3x 11x 13
815:5x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 11x 13 = 4719
Therefore, the value for common factors is 4719.
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 = 138593915460/(1x4719)
LCM = 138593915460/4719
LCM = 29369340
Thus, we can understand that the LCM of 693,572,429,815 is 29369340.
