Given numbers are 407,363,817,977
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 407,363,817,977 is 10720745079.
Find LCM of 407,363,817,977 with Prime Factorization
| 11 | 407, 363, 817, 977 |
| 37, 33, 817, 977 |
Multiply the prime numbers at the bottom and the left side.
11 x 37 x 33 x 817 x 977 = 10720745079
Therefore, the lowest common multiple of 407,363,817,977 is 10720745079.
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.
407 x 363 x 817 x 977 = 117928195869
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.
407 : 1, 11, 37, 407
363 : 1, 3, 11, 33, 121, 363
817 : 1, 19, 43, 817
977 : 1, 977
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,363,817,977, is 1.
Now, the common factors can be found like this.
407:11x 37
363:3x 11x 11
817:19x 43
977:977
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 117928195869/(1x11)
LCM = 117928195869/11
LCM = 10720745079
Thus, we can understand that the LCM of 407,363,817,977 is 10720745079.
