Given numbers are 723,695,605,456,298
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 723,695,605,456,298 is 1377013913880.
Find LCM of 723,695,605,456,298 with Prime Factorization
| 2 | 723, 695, 605, 456, 298 |
| 3 | 723, 695, 605, 228, 149 |
| 5 | 241, 695, 605, 76, 149 |
| 241, 139, 121, 76, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 241 x 139 x 121 x 76 x 149 = 1377013913880
Therefore, the lowest common multiple of 723,695,605,456,298 is 1377013913880.
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.
723 x 695 x 605 x 456 x 298 = 41310417416400
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.
723 : 1, 3, 241, 723
695 : 1, 5, 139, 695
605 : 1, 5, 11, 55, 121, 605
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
298 : 1, 2, 149, 298
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 723,695,605,456,298, is 1.
Now, the common factors can be found like this.
723:3x 241
695:5x 139
605:5x 11x 11
456:2x 2x 2x 3x 19
298:2x 149
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 5 = 30
Therefore, the value for common factors is 30.
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 = 41310417416400/(1x30)
LCM = 41310417416400/30
LCM = 1377013913880
Thus, we can understand that the LCM of 723,695,605,456,298 is 1377013913880.
