Given numbers are 473,642,847,284
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 473,642,847,284 is 3320284044.
Find LCM of 473,642,847,284 with Prime Factorization
| 2 | 473, 642, 847, 284 |
| 11 | 473, 321, 847, 142 |
| 43, 321, 77, 142 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 43 x 321 x 77 x 142 = 3320284044
Therefore, the lowest common multiple of 473,642,847,284 is 3320284044.
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 642 x 847 x 284 = 73046248968
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
642 : 1, 2, 3, 6, 107, 214, 321, 642
847 : 1, 7, 11, 77, 121, 847
284 : 1, 2, 4, 71, 142, 284
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 473,642,847,284, is 1.
Now, the common factors can be found like this.
473:11x 43
642:2x 3x 107
847:7x 11x 11
284:2x 2x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 73046248968/(1x22)
LCM = 73046248968/22
LCM = 3320284044
Thus, we can understand that the LCM of 473,642,847,284 is 3320284044.
