Find LCM of 785,546,931,399,347 with Prime Factorization
| 3 | 785, 546, 931, 399, 347 |
| 7 | 785, 182, 931, 133, 347 |
| 19 | 785, 26, 19, 133, 347 |
| 785, 26, 1, 7, 347 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 19 x 785 x 26 x 1 x 7 x 347 = 19780780110
Therefore, the lowest common multiple of 785,546,931,399,347 is 19780780110.
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.
785 x 546 x 931 x 399 x 347 = 55247718847230
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.
785 : 1, 5, 157, 785
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
931 : 1, 7, 19, 49, 133, 931
399 : 1, 3, 7, 19, 21, 57, 133, 399
347 : 1, 347
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,546,931,399,347, is 1.
Now, the common factors can be found like this.
785:5x 157
546:2x 3x 7x 13
931:7x 7x 19
399:3x 7x 19
347:347
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 7x 19 = 2793
Therefore, the value for common factors is 2793.
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 = 55247718847230/(1x2793)
LCM = 55247718847230/2793
LCM = 19780780110
Thus, we can understand that the LCM of 785,546,931,399,347 is 19780780110.
