Given numbers are 647,911,668,294
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 647,911,668,294 is 57878391732.
Find LCM of 647,911,668,294 with Prime Factorization
| 2 | 647, 911, 668, 294 |
| 647, 911, 334, 147 |
Multiply the prime numbers at the bottom and the left side.
2 x 647 x 911 x 334 x 147 = 57878391732
Therefore, the lowest common multiple of 647,911,668,294 is 57878391732.
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.
647 x 911 x 668 x 294 = 115756783464
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.
647 : 1, 647
911 : 1, 911
668 : 1, 2, 4, 167, 334, 668
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,911,668,294, is 1.
Now, the common factors can be found like this.
647:647
911:911
668:2x 2x 167
294:2x 3x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 115756783464/(1x2)
LCM = 115756783464/2
LCM = 57878391732
Thus, we can understand that the LCM of 647,911,668,294 is 57878391732.
