Given numbers are 101,657,763,756,809
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 101,657,763,756,809 is 491519835828.
Find LCM of 101,657,763,756,809 with Prime Factorization
| 3 | 101, 657, 763, 756, 809 |
| 3 | 101, 219, 763, 252, 809 |
| 7 | 101, 73, 763, 84, 809 |
| 101, 73, 109, 12, 809 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 101 x 73 x 109 x 12 x 809 = 491519835828
Therefore, the lowest common multiple of 101,657,763,756,809 is 491519835828.
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.
101 x 657 x 763 x 756 x 809 = 30965749657164
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.
101 : 1, 101
657 : 1, 3, 9, 73, 219, 657
763 : 1, 7, 109, 763
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
809 : 1, 809
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 101,657,763,756,809, is 1.
Now, the common factors can be found like this.
101:101
657:3x 3x 73
763:7x 109
756:2x 2x 3x 3x 3x 7
809:809
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 7 = 63
Therefore, the value for common factors is 63.
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 = 30965749657164/(1x63)
LCM = 30965749657164/63
LCM = 491519835828
Thus, we can understand that the LCM of 101,657,763,756,809 is 491519835828.
