Given numbers are 874,174,745,782,284
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 874,174,745,782,284 is 136749020340.
Find LCM of 874,174,745,782,284 with Prime Factorization
| 2 | 874, 174, 745, 782, 284 |
| 23 | 437, 87, 745, 391, 142 |
| 19, 87, 745, 17, 142 |
Multiply the prime numbers at the bottom and the left side.
2 x 23 x 19 x 87 x 745 x 17 x 142 = 136749020340
Therefore, the lowest common multiple of 874,174,745,782,284 is 136749020340.
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.
874 x 174 x 745 x 782 x 284 = 25161819742560
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.
874 : 1, 2, 19, 23, 38, 46, 437, 874
174 : 1, 2, 3, 6, 29, 58, 87, 174
745 : 1, 5, 149, 745
782 : 1, 2, 17, 23, 34, 46, 391, 782
284 : 1, 2, 4, 71, 142, 284
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,174,745,782,284, is 1.
Now, the common factors can be found like this.
874:2x 19x 23
174:2x 3x 29
745:5x 149
782:2x 17x 23
284:2x 2x 71
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 23 = 184
Therefore, the value for common factors is 184.
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 = 25161819742560/(1x184)
LCM = 25161819742560/184
LCM = 136749020340
Thus, we can understand that the LCM of 874,174,745,782,284 is 136749020340.
