Given numbers are 473,782,385,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 473,782,385,840 is 155352120.
Find LCM of 473,782,385,840 with Prime Factorization
| 2 | 473, 782, 385, 840 |
| 5 | 473, 391, 385, 420 |
| 7 | 473, 391, 77, 84 |
| 11 | 473, 391, 11, 12 |
| 43, 391, 1, 12 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 43 x 391 x 1 x 12 = 155352120
Therefore, the lowest common multiple of 473,782,385,840 is 155352120.
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.
473 x 782 x 385 x 840 = 119621132400
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.
473 : 1, 11, 43, 473
782 : 1, 2, 17, 23, 34, 46, 391, 782
385 : 1, 5, 7, 11, 35, 55, 77, 385
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 473,782,385,840, is 1.
Now, the common factors can be found like this.
473:11x 43
782:2x 17x 23
385:5x 7x 11
840:2x 2x 2x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 11 = 770
Therefore, the value for common factors is 770.
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 = 119621132400/(1x770)
LCM = 119621132400/770
LCM = 155352120
Thus, we can understand that the LCM of 473,782,385,840 is 155352120.
