Given numbers are 462,980,574,942
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 462,980,574,942 is 208172580.
Find LCM of 462,980,574,942 with Prime Factorization
| 2 | 462, 980, 574, 942 |
| 3 | 231, 490, 287, 471 |
| 7 | 77, 490, 287, 157 |
| 11, 70, 41, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 70 x 41 x 157 = 208172580
Therefore, the lowest common multiple of 462,980,574,942 is 208172580.
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.
462 x 980 x 574 x 942 = 244810954080
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.
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
574 : 1, 2, 7, 14, 41, 82, 287, 574
942 : 1, 2, 3, 6, 157, 314, 471, 942
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 462,980,574,942, is 2.
Now, the common factors can be found like this.
462:2x 3x 7x 11
980:2x 2x 5x 7x 7
574:2x 7x 41
942:2x 3x 157
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 7x 7 = 588
Therefore, the value for common factors is 588.
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 = 244810954080/(2x588)
LCM = 244810954080/1176
LCM = 208172580
Thus, we can understand that the LCM of 462,980,574,942 is 208172580.
