Given numbers are 699,436,654,320
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 699,436,654,320 is 24381120.
Find LCM of 699,436,654,320 with Prime Factorization
| 2 | 699, 436, 654, 320 |
| 2 | 699, 218, 327, 160 |
| 3 | 699, 109, 327, 80 |
| 109 | 233, 109, 109, 80 |
| 233, 1, 1, 80 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 109 x 233 x 1 x 1 x 80 = 24381120
Therefore, the lowest common multiple of 699,436,654,320 is 24381120.
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.
699 x 436 x 654 x 320 = 63781009920
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.
699 : 1, 3, 233, 699
436 : 1, 2, 4, 109, 218, 436
654 : 1, 2, 3, 6, 109, 218, 327, 654
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 699,436,654,320, is 1.
Now, the common factors can be found like this.
699:3x 233
436:2x 2x 109
654:2x 3x 109
320:2x 2x 2x 2x 2x 2x 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 2x 3x 109 = 2616
Therefore, the value for common factors is 2616.
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 = 63781009920/(1x2616)
LCM = 63781009920/2616
LCM = 24381120
Thus, we can understand that the LCM of 699,436,654,320 is 24381120.
