Given numbers are 846,409,621,786,254
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 846,409,621,786,254 is 397207809342.
Find LCM of 846,409,621,786,254 with Prime Factorization
| 2 | 846, 409, 621, 786, 254 |
| 3 | 423, 409, 621, 393, 127 |
| 3 | 141, 409, 207, 131, 127 |
| 47, 409, 69, 131, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 47 x 409 x 69 x 131 x 127 = 397207809342
Therefore, the lowest common multiple of 846,409,621,786,254 is 397207809342.
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.
846 x 409 x 621 x 786 x 254 = 42898443408936
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.
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
409 : 1, 409
621 : 1, 3, 9, 23, 27, 69, 207, 621
786 : 1, 2, 3, 6, 131, 262, 393, 786
254 : 1, 2, 127, 254
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 846,409,621,786,254, is 1.
Now, the common factors can be found like this.
846:2x 3x 3x 47
409:409
621:3x 3x 3x 23
786:2x 3x 131
254:2x 127
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 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 42898443408936/(1x108)
LCM = 42898443408936/108
LCM = 397207809342
Thus, we can understand that the LCM of 846,409,621,786,254 is 397207809342.
