Given numbers are 298,121,945,770,919
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 298,121,945,770,919 is 31314750390.
Find LCM of 298,121,945,770,919 with Prime Factorization
| 2 | 298, 121, 945, 770, 919 |
| 5 | 149, 121, 945, 385, 919 |
| 7 | 149, 121, 189, 77, 919 |
| 11 | 149, 121, 27, 11, 919 |
| 149, 1, 27, 11, 919 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 149 x 1 x 27 x 11 x 919 = 31314750390
Therefore, the lowest common multiple of 298,121,945,770,919 is 31314750390.
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.
298 x 121 x 945 x 770 x 919 = 24112357800300
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.
298 : 1, 2, 149, 298
121 : 1, 11, 121
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
919 : 1, 919
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 298,121,945,770,919, is 1.
Now, the common factors can be found like this.
298:2x 149
121:11x 11
945:3x 3x 3x 5x 7
770:2x 5x 7x 11
919:919
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 7x 11 = 770
Therefore, the value for common factors is 770.
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 = 24112357800300/(1x770)
LCM = 24112357800300/770
LCM = 31314750390
Thus, we can understand that the LCM of 298,121,945,770,919 is 31314750390.
