Given numbers are 422,734,217,143,740
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 422,734,217,143,740 is 1778181184780.
Find LCM of 422,734,217,143,740 with Prime Factorization
2 | 422, 734, 217, 143, 740 |
211, 367, 217, 143, 370 |
Multiply the prime numbers at the bottom and the left side.
2 x 211 x 367 x 217 x 143 x 370 = 1778181184780
Therefore, the lowest common multiple of 422,734,217,143,740 is 1778181184780.
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.
422 x 734 x 217 x 143 x 740 = 7112724739120
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.
422 : 1, 2, 211, 422
734 : 1, 2, 367, 734
217 : 1, 7, 31, 217
143 : 1, 11, 13, 143
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,734,217,143,740, is 1.
Now, the common factors can be found like this.
422:2x 211
734:2x 367
217:7x 31
143:11x 13
740:2x 2x 5x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 7112724739120/(1x4)
LCM = 7112724739120/4
LCM = 1778181184780
Thus, we can understand that the LCM of 422,734,217,143,740 is 1778181184780.
