Given numbers are 691,611,624,410
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 691,611,624,410 is 4154457840.
Find LCM of 691,611,624,410 with Prime Factorization
| 2 | 691, 611, 624, 410 |
| 13 | 691, 611, 312, 205 |
| 691, 47, 24, 205 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 691 x 47 x 24 x 205 = 4154457840
Therefore, the lowest common multiple of 691,611,624,410 is 4154457840.
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.
691 x 611 x 624 x 410 = 108015903840
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.
691 : 1, 691
611 : 1, 13, 47, 611
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
410 : 1, 2, 5, 10, 41, 82, 205, 410
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,611,624,410, is 1.
Now, the common factors can be found like this.
691:691
611:13x 47
624:2x 2x 2x 2x 3x 13
410:2x 5x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13 = 26
Therefore, the value for common factors is 26.
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 = 108015903840/(1x26)
LCM = 108015903840/26
LCM = 4154457840
Thus, we can understand that the LCM of 691,611,624,410 is 4154457840.
