Given numbers are 954,748,789,620
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 954,748,789,620 is 14544788940.
Find LCM of 954,748,789,620 with Prime Factorization
| 2 | 954, 748, 789, 620 |
| 2 | 477, 374, 789, 310 |
| 3 | 477, 187, 789, 155 |
| 159, 187, 263, 155 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 159 x 187 x 263 x 155 = 14544788940
Therefore, the lowest common multiple of 954,748,789,620 is 14544788940.
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.
954 x 748 x 789 x 620 = 349074934560
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.
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
789 : 1, 3, 263, 789
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 954,748,789,620, is 1.
Now, the common factors can be found like this.
954:2x 3x 3x 53
748:2x 2x 11x 17
789:3x 263
620:2x 2x 5x 31
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 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 349074934560/(1x24)
LCM = 349074934560/24
LCM = 14544788940
Thus, we can understand that the LCM of 954,748,789,620 is 14544788940.
