Find LCM of 972,889,778,261,309 with Prime Factorization
2 | 972, 889, 778, 261, 309 |
3 | 486, 889, 389, 261, 309 |
3 | 162, 889, 389, 87, 103 |
54, 889, 389, 29, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 54 x 889 x 389 x 29 x 103 = 1004044241844
Therefore, the lowest common multiple of 972,889,778,261,309 is 1004044241844.
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.
972 x 889 x 778 x 261 x 309 = 54218389059576
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.
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
889 : 1, 7, 127, 889
778 : 1, 2, 389, 778
261 : 1, 3, 9, 29, 87, 261
309 : 1, 3, 103, 309
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,889,778,261,309, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
889:7x 127
778:2x 389
261:3x 3x 29
309:3x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3 = 54
Therefore, the value for common factors is 54.
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 = 54218389059576/(1x54)
LCM = 54218389059576/54
LCM = 1004044241844
Thus, we can understand that the LCM of 972,889,778,261,309 is 1004044241844.
