Given numbers are 578,159,334,646,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,159,334,646,781 is 227743540926.
Find LCM of 578,159,334,646,781 with Prime Factorization
2 | 578, 159, 334, 646, 781 |
17 | 289, 159, 167, 323, 781 |
17, 159, 167, 19, 781 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 17 x 159 x 167 x 19 x 781 = 227743540926
Therefore, the lowest common multiple of 578,159,334,646,781 is 227743540926.
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.
578 x 159 x 334 x 646 x 781 = 15486560782968
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.
578 : 1, 2, 17, 34, 289, 578
159 : 1, 3, 53, 159
334 : 1, 2, 167, 334
646 : 1, 2, 17, 19, 34, 38, 323, 646
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,159,334,646,781, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
159:3x 53
334:2x 167
646:2x 17x 19
781:11x 71
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 17 = 68
Therefore, the value for common factors is 68.
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 = 15486560782968/(1x68)
LCM = 15486560782968/68
LCM = 227743540926
Thus, we can understand that the LCM of 578,159,334,646,781 is 227743540926.
