Given numbers are 950,621,742,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 950,621,742,138 is 218871450.
Find LCM of 950,621,742,138 with Prime Factorization
| 2 | 950, 621, 742, 138 |
| 3 | 475, 621, 371, 69 |
| 23 | 475, 207, 371, 23 |
| 475, 9, 371, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 475 x 9 x 371 x 1 = 218871450
Therefore, the lowest common multiple of 950,621,742,138 is 218871450.
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.
950 x 621 x 742 x 138 = 60408520200
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.
950 : 1, 2, 5, 10, 19, 25, 38, 50, 95, 190, 475, 950
621 : 1, 3, 9, 23, 27, 69, 207, 621
742 : 1, 2, 7, 14, 53, 106, 371, 742
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 950,621,742,138, is 1.
Now, the common factors can be found like this.
950:2x 5x 5x 19
621:3x 3x 3x 23
742:2x 7x 53
138:2x 3x 23
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 3x 23 = 276
Therefore, the value for common factors is 276.
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 = 60408520200/(1x276)
LCM = 60408520200/276
LCM = 218871450
Thus, we can understand that the LCM of 950,621,742,138 is 218871450.
