Given numbers are 142,389,772,736,753
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 142,389,772,736,753 is 2954187455136.
Find LCM of 142,389,772,736,753 with Prime Factorization
| 2 | 142, 389, 772, 736, 753 |
| 2 | 71, 389, 386, 368, 753 |
| 71, 389, 193, 184, 753 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 71 x 389 x 193 x 184 x 753 = 2954187455136
Therefore, the lowest common multiple of 142,389,772,736,753 is 2954187455136.
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.
142 x 389 x 772 x 736 x 753 = 23633499641088
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.
142 : 1, 2, 71, 142
389 : 1, 389
772 : 1, 2, 4, 193, 386, 772
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
753 : 1, 3, 251, 753
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,389,772,736,753, is 1.
Now, the common factors can be found like this.
142:2x 71
389:389
772:2x 2x 193
736:2x 2x 2x 2x 2x 23
753:3x 251
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 2 = 8
Therefore, the value for common factors is 8.
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 = 23633499641088/(1x8)
LCM = 23633499641088/8
LCM = 2954187455136
Thus, we can understand that the LCM of 142,389,772,736,753 is 2954187455136.
