The LCM of 724,546,534,782,238 is 6878091948.
Find LCM of 724,546,534,782,238 with Prime Factorization
| 2 | 724, 546, 534, 782, 238 |
| 3 | 362, 273, 267, 391, 119 |
| 7 | 362, 91, 89, 391, 119 |
| 17 | 362, 13, 89, 391, 17 |
| 362, 13, 89, 23, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 17 x 362 x 13 x 89 x 23 x 1 = 6878091948
Therefore, the lowest common multiple of 724,546,534,782,238 is 6878091948.
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.
724 x 546 x 534 x 782 x 238 = 39287661206976
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.
724 : 1, 2, 4, 181, 362, 724
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
534 : 1, 2, 3, 6, 89, 178, 267, 534
782 : 1, 2, 17, 23, 34, 46, 391, 782
238 : 1, 2, 7, 14, 17, 34, 119, 238
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,546,534,782,238, is 2.
Now, the common factors can be found like this.
724:2x 2x 181
546:2x 3x 7x 13
534:2x 3x 89
782:2x 17x 23
238:2x 7x 17
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 7x 17 = 2856
Therefore, the value for common factors is 2856.
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 = 39287661206976/(2x2856)
LCM = 39287661206976/5712
LCM = 6878091948
Thus, we can understand that the LCM of 724,546,534,782,238 is 6878091948.
