Given numbers are 783,537,639,284
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 783,537,639,284 is 39804588.
Find LCM of 783,537,639,284 with Prime Factorization
| 3 | 783, 537, 639, 284 |
| 3 | 261, 179, 213, 284 |
| 71 | 87, 179, 71, 284 |
| 87, 179, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 71 x 87 x 179 x 1 x 4 = 39804588
Therefore, the lowest common multiple of 783,537,639,284 is 39804588.
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.
783 x 537 x 639 x 284 = 76305395196
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.
783 : 1, 3, 9, 27, 29, 87, 261, 783
537 : 1, 3, 179, 537
639 : 1, 3, 9, 71, 213, 639
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 783,537,639,284, is 1.
Now, the common factors can be found like this.
783:3x 3x 3x 29
537:3x 179
639:3x 3x 71
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.
3x 3x 3x 71 = 1917
Therefore, the value for common factors is 1917.
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 = 76305395196/(1x1917)
LCM = 76305395196/1917
LCM = 39804588
Thus, we can understand that the LCM of 783,537,639,284 is 39804588.
