Given numbers are 157,485,735,220,428
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 157,485,735,220,428 is 52698127020.
Find LCM of 157,485,735,220,428 with Prime Factorization
| 2 | 157, 485, 735, 220, 428 |
| 2 | 157, 485, 735, 110, 214 |
| 5 | 157, 485, 735, 55, 107 |
| 157, 97, 147, 11, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 157 x 97 x 147 x 11 x 107 = 52698127020
Therefore, the lowest common multiple of 157,485,735,220,428 is 52698127020.
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.
157 x 485 x 735 x 220 x 428 = 5269812702000
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.
157 : 1, 157
485 : 1, 5, 97, 485
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
428 : 1, 2, 4, 107, 214, 428
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,485,735,220,428, is 1.
Now, the common factors can be found like this.
157:157
485:5x 97
735:3x 5x 7x 7
220:2x 2x 5x 11
428:2x 2x 107
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 5x 5 = 100
Therefore, the value for common factors is 100.
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 = 5269812702000/(1x100)
LCM = 5269812702000/100
LCM = 52698127020
Thus, we can understand that the LCM of 157,485,735,220,428 is 52698127020.
