Given numbers are 782,709,148,140,154
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 782,709,148,140,154 is 15795938620.
Find LCM of 782,709,148,140,154 with Prime Factorization
| 2 | 782, 709, 148, 140, 154 |
| 2 | 391, 709, 74, 70, 77 |
| 7 | 391, 709, 37, 35, 77 |
| 391, 709, 37, 5, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 391 x 709 x 37 x 5 x 11 = 15795938620
Therefore, the lowest common multiple of 782,709,148,140,154 is 15795938620.
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.
782 x 709 x 148 x 140 x 154 = 1769145125440
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
709 : 1, 709
148 : 1, 2, 4, 37, 74, 148
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,709,148,140,154, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
709:709
148:2x 2x 37
140:2x 2x 5x 7
154:2x 7x 11
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 2x 7 = 112
Therefore, the value for common factors is 112.
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 = 1769145125440/(1x112)
LCM = 1769145125440/112
LCM = 15795938620
Thus, we can understand that the LCM of 782,709,148,140,154 is 15795938620.
