Given numbers are 721,361,245,774,347
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,361,245,774,347 is 2446701264630.
Find LCM of 721,361,245,774,347 with Prime Factorization
| 7 | 721, 361, 245, 774, 347 |
| 103, 361, 35, 774, 347 |
Multiply the prime numbers at the bottom and the left side.
7 x 103 x 361 x 35 x 774 x 347 = 2446701264630
Therefore, the lowest common multiple of 721,361,245,774,347 is 2446701264630.
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.
721 x 361 x 245 x 774 x 347 = 17126908852410
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.
721 : 1, 7, 103, 721
361 : 1, 19, 361
245 : 1, 5, 7, 35, 49, 245
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
347 : 1, 347
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,361,245,774,347, is 1.
Now, the common factors can be found like this.
721:7x 103
361:19x 19
245:5x 7x 7
774:2x 3x 3x 43
347:347
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 17126908852410/(1x7)
LCM = 17126908852410/7
LCM = 2446701264630
Thus, we can understand that the LCM of 721,361,245,774,347 is 2446701264630.
