Given numbers are 257,263,962,780,785
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 257,263,962,780,785 is 306256172820.
Find LCM of 257,263,962,780,785 with Prime Factorization
| 2 | 257, 263, 962, 780, 785 |
| 5 | 257, 263, 481, 390, 785 |
| 13 | 257, 263, 481, 78, 157 |
| 257, 263, 37, 6, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 257 x 263 x 37 x 6 x 157 = 306256172820
Therefore, the lowest common multiple of 257,263,962,780,785 is 306256172820.
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.
257 x 263 x 962 x 780 x 785 = 39813302466600
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.
257 : 1, 257
263 : 1, 263
962 : 1, 2, 13, 26, 37, 74, 481, 962
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
785 : 1, 5, 157, 785
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,263,962,780,785, is 1.
Now, the common factors can be found like this.
257:257
263:263
962:2x 13x 37
780:2x 2x 3x 5x 13
785:5x 157
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 13 = 130
Therefore, the value for common factors is 130.
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 = 39813302466600/(1x130)
LCM = 39813302466600/130
LCM = 306256172820
Thus, we can understand that the LCM of 257,263,962,780,785 is 306256172820.
