Given numbers are 692,168,973,169
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 692,168,973,169 is 682742424.
Find LCM of 692,168,973,169 with Prime Factorization
| 2 | 692, 168, 973, 169 |
| 2 | 346, 84, 973, 169 |
| 7 | 173, 42, 973, 169 |
| 173, 6, 139, 169 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 173 x 6 x 139 x 169 = 682742424
Therefore, the lowest common multiple of 692,168,973,169 is 682742424.
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.
692 x 168 x 973 x 169 = 19116787872
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.
692 : 1, 2, 4, 173, 346, 692
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
973 : 1, 7, 139, 973
169 : 1, 13, 169
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 692,168,973,169, is 1.
Now, the common factors can be found like this.
692:2x 2x 173
168:2x 2x 2x 3x 7
973:7x 139
169:13x 13
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 7 = 28
Therefore, the value for common factors is 28.
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 = 19116787872/(1x28)
LCM = 19116787872/28
LCM = 682742424
Thus, we can understand that the LCM of 692,168,973,169 is 682742424.
