The LCM of 385,483,782,423,947 is 120602921670.
Find LCM of 385,483,782,423,947 with Prime Factorization
| 3 | 385, 483, 782, 423, 947 |
| 7 | 385, 161, 782, 141, 947 |
| 23 | 55, 23, 782, 141, 947 |
| 55, 1, 34, 141, 947 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 23 x 55 x 1 x 34 x 141 x 947 = 120602921670
Therefore, the lowest common multiple of 385,483,782,423,947 is 120602921670.
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.
385 x 483 x 782 x 423 x 947 = 58251211166610
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.
385 : 1, 5, 7, 11, 35, 55, 77, 385
483 : 1, 3, 7, 21, 23, 69, 161, 483
782 : 1, 2, 17, 23, 34, 46, 391, 782
423 : 1, 3, 9, 47, 141, 423
947 : 1, 947
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 385,483,782,423,947, is 1.
Now, the common factors can be found like this.
385:5x 7x 11
483:3x 7x 23
782:2x 17x 23
423:3x 3x 47
947:947
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 23 = 483
Therefore, the value for common factors is 483.
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 = 58251211166610/(1x483)
LCM = 58251211166610/483
LCM = 120602921670
Thus, we can understand that the LCM of 385,483,782,423,947 is 120602921670.
