Given numbers are 408,786,499,781,767
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 408,786,499,781,767 is 15976380752904.
Find LCM of 408,786,499,781,767 with Prime Factorization
| 2 | 408, 786, 499, 781, 767 |
| 3 | 204, 393, 499, 781, 767 |
| 68, 131, 499, 781, 767 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 68 x 131 x 499 x 781 x 767 = 15976380752904
Therefore, the lowest common multiple of 408,786,499,781,767 is 15976380752904.
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.
408 x 786 x 499 x 781 x 767 = 95858284517424
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.
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
786 : 1, 2, 3, 6, 131, 262, 393, 786
499 : 1, 499
781 : 1, 11, 71, 781
767 : 1, 13, 59, 767
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 408,786,499,781,767, is 1.
Now, the common factors can be found like this.
408:2x 2x 2x 3x 17
786:2x 3x 131
499:499
781:11x 71
767:13x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 95858284517424/(1x6)
LCM = 95858284517424/6
LCM = 15976380752904
Thus, we can understand that the LCM of 408,786,499,781,767 is 15976380752904.
