Given numbers are 478,700,169,445,945
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 478,700,169,445,945 is 67941701100.
Find LCM of 478,700,169,445,945 with Prime Factorization
| 2 | 478, 700, 169, 445, 945 |
| 5 | 239, 350, 169, 445, 945 |
| 7 | 239, 70, 169, 89, 189 |
| 239, 10, 169, 89, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 239 x 10 x 169 x 89 x 27 = 67941701100
Therefore, the lowest common multiple of 478,700,169,445,945 is 67941701100.
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.
478 x 700 x 169 x 445 x 945 = 23779595385000
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.
478 : 1, 2, 239, 478
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
169 : 1, 13, 169
445 : 1, 5, 89, 445
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,700,169,445,945, is 1.
Now, the common factors can be found like this.
478:2x 239
700:2x 2x 5x 5x 7
169:13x 13
445:5x 89
945:3x 3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 7 = 350
Therefore, the value for common factors is 350.
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 = 23779595385000/(1x350)
LCM = 23779595385000/350
LCM = 67941701100
Thus, we can understand that the LCM of 478,700,169,445,945 is 67941701100.
