Given numbers are 868,403,802,564
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 868,403,802,564 is 638008644.
Find LCM of 868,403,802,564 with Prime Factorization
| 2 | 868, 403, 802, 564 |
| 2 | 434, 403, 401, 282 |
| 31 | 217, 403, 401, 141 |
| 7, 13, 401, 141 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 31 x 7 x 13 x 401 x 141 = 638008644
Therefore, the lowest common multiple of 868,403,802,564 is 638008644.
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.
868 x 403 x 802 x 564 = 158226143712
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.
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
403 : 1, 13, 31, 403
802 : 1, 2, 401, 802
564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 868,403,802,564, is 1.
Now, the common factors can be found like this.
868:2x 2x 7x 31
403:13x 31
802:2x 401
564:2x 2x 3x 47
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 31 = 248
Therefore, the value for common factors is 248.
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 = 158226143712/(1x248)
LCM = 158226143712/248
LCM = 638008644
Thus, we can understand that the LCM of 868,403,802,564 is 638008644.
