Given numbers are 212,817,651,688
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 212,817,651,688 is 451023216.
Find LCM of 212,817,651,688 with Prime Factorization
2 | 212, 817, 651, 688 |
2 | 106, 817, 651, 344 |
43 | 53, 817, 651, 172 |
53, 19, 651, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 43 x 53 x 19 x 651 x 4 = 451023216
Therefore, the lowest common multiple of 212,817,651,688 is 451023216.
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.
212 x 817 x 651 x 688 = 77575993152
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.
212 : 1, 2, 4, 53, 106, 212
817 : 1, 19, 43, 817
651 : 1, 3, 7, 21, 31, 93, 217, 651
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 212,817,651,688, is 1.
Now, the common factors can be found like this.
212:2x 2x 53
817:19x 43
651:3x 7x 31
688:2x 2x 2x 2x 43
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 43 = 172
Therefore, the value for common factors is 172.
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 = 77575993152/(1x172)
LCM = 77575993152/172
LCM = 451023216
Thus, we can understand that the LCM of 212,817,651,688 is 451023216.
