Given numbers are 742,886,350,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 742,886,350,220 is 180788300.
Find LCM of 742,886,350,220 with Prime Factorization
| 2 | 742, 886, 350, 220 |
| 5 | 371, 443, 175, 110 |
| 7 | 371, 443, 35, 22 |
| 53, 443, 5, 22 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 53 x 443 x 5 x 22 = 180788300
Therefore, the lowest common multiple of 742,886,350,220 is 180788300.
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.
742 x 886 x 350 x 220 = 50620724000
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.
742 : 1, 2, 7, 14, 53, 106, 371, 742
886 : 1, 2, 443, 886
350 : 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,886,350,220, is 2.
Now, the common factors can be found like this.
742:2x 7x 53
886:2x 443
350:2x 5x 5x 7
220:2x 2x 5x 11
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 5x 7 = 140
Therefore, the value for common factors is 140.
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 = 50620724000/(2x140)
LCM = 50620724000/280
LCM = 180788300
Thus, we can understand that the LCM of 742,886,350,220 is 180788300.
