Given numbers are 745,764,830,829,684
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 745,764,830,829,684 is 6696970172460.
Find LCM of 745,764,830,829,684 with Prime Factorization
| 2 | 745, 764, 830, 829, 684 |
| 2 | 745, 382, 415, 829, 342 |
| 5 | 745, 191, 415, 829, 171 |
| 149, 191, 83, 829, 171 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 149 x 191 x 83 x 829 x 171 = 6696970172460
Therefore, the lowest common multiple of 745,764,830,829,684 is 6696970172460.
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.
745 x 764 x 830 x 829 x 684 = 267878806898400
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.
745 : 1, 5, 149, 745
764 : 1, 2, 4, 191, 382, 764
830 : 1, 2, 5, 10, 83, 166, 415, 830
829 : 1, 829
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 745,764,830,829,684, is 1.
Now, the common factors can be found like this.
745:5x 149
764:2x 2x 191
830:2x 5x 83
829:829
684:2x 2x 3x 3x 19
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 2x 5 = 40
Therefore, the value for common factors is 40.
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 = 267878806898400/(1x40)
LCM = 267878806898400/40
LCM = 6696970172460
Thus, we can understand that the LCM of 745,764,830,829,684 is 6696970172460.
