Given numbers are 438,334,738,862,668
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 438,334,738,862,668 is 7755377796.
Find LCM of 438,334,738,862,668 with Prime Factorization
| 2 | 438, 334, 738, 862, 668 |
| 3 | 219, 167, 369, 431, 334 |
| 167 | 73, 167, 123, 431, 334 |
| 73, 1, 123, 431, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 167 x 73 x 1 x 123 x 431 x 2 = 7755377796
Therefore, the lowest common multiple of 438,334,738,862,668 is 7755377796.
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.
438 x 334 x 738 x 862 x 668 = 62167108412736
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.
438 : 1, 2, 3, 6, 73, 146, 219, 438
334 : 1, 2, 167, 334
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
862 : 1, 2, 431, 862
668 : 1, 2, 4, 167, 334, 668
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,334,738,862,668, is 2.
Now, the common factors can be found like this.
438:2x 3x 73
334:2x 167
738:2x 3x 3x 41
862:2x 431
668:2x 2x 167
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 3x 167 = 4008
Therefore, the value for common factors is 4008.
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 = 62167108412736/(2x4008)
LCM = 62167108412736/8016
LCM = 7755377796
Thus, we can understand that the LCM of 438,334,738,862,668 is 7755377796.
