Given numbers are 681,247,470,329
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 681,247,470,329 is 553401030.
Find LCM of 681,247,470,329 with Prime Factorization
| 47 | 681, 247, 470, 329 |
| 681, 247, 10, 7 |
Multiply the prime numbers at the bottom and the left side.
47 x 681 x 247 x 10 x 7 = 553401030
Therefore, the lowest common multiple of 681,247,470,329 is 553401030.
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.
681 x 247 x 470 x 329 = 26009848410
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.
681 : 1, 3, 227, 681
247 : 1, 13, 19, 247
470 : 1, 2, 5, 10, 47, 94, 235, 470
329 : 1, 7, 47, 329
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,247,470,329, is 1.
Now, the common factors can be found like this.
681:3x 227
247:13x 19
470:2x 5x 47
329:7x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
47 = 47
Therefore, the value for common factors is 47.
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 = 26009848410/(1x47)
LCM = 26009848410/47
LCM = 553401030
Thus, we can understand that the LCM of 681,247,470,329 is 553401030.
