Given numbers are 826,100,390,611
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 826,100,390,611 is 75702900.
Find LCM of 826,100,390,611 with Prime Factorization
| 2 | 826, 100, 390, 611 |
| 5 | 413, 50, 195, 611 |
| 13 | 413, 10, 39, 611 |
| 413, 10, 3, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 413 x 10 x 3 x 47 = 75702900
Therefore, the lowest common multiple of 826,100,390,611 is 75702900.
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.
826 x 100 x 390 x 611 = 19682754000
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.
826 : 1, 2, 7, 14, 59, 118, 413, 826
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
611 : 1, 13, 47, 611
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 826,100,390,611, is 1.
Now, the common factors can be found like this.
826:2x 7x 59
100:2x 2x 5x 5
390:2x 3x 5x 13
611:13x 47
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 5x 13 = 260
Therefore, the value for common factors is 260.
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 = 19682754000/(1x260)
LCM = 19682754000/260
LCM = 75702900
Thus, we can understand that the LCM of 826,100,390,611 is 75702900.
