Given numbers are 843,851,620,331,786
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 843,851,620,331,786 is 19286264281260.
Find LCM of 843,851,620,331,786 with Prime Factorization
| 2 | 843, 851, 620, 331, 786 |
| 3 | 843, 851, 310, 331, 393 |
| 281, 851, 310, 331, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 281 x 851 x 310 x 331 x 131 = 19286264281260
Therefore, the lowest common multiple of 843,851,620,331,786 is 19286264281260.
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.
843 x 851 x 620 x 331 x 786 = 115717585687560
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.
843 : 1, 3, 281, 843
851 : 1, 23, 37, 851
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
331 : 1, 331
786 : 1, 2, 3, 6, 131, 262, 393, 786
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,851,620,331,786, is 1.
Now, the common factors can be found like this.
843:3x 281
851:23x 37
620:2x 2x 5x 31
331:331
786:2x 3x 131
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 = 115717585687560/(1x6)
LCM = 115717585687560/6
LCM = 19286264281260
Thus, we can understand that the LCM of 843,851,620,331,786 is 19286264281260.
