Given numbers are 749,731,430,602
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 749,731,430,602 is 5475190.
Find LCM of 749,731,430,602 with Prime Factorization
| 2 | 749, 731, 430, 602 |
| 7 | 749, 731, 215, 301 |
| 43 | 107, 731, 215, 43 |
| 107, 17, 5, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 43 x 107 x 17 x 5 x 1 = 5475190
Therefore, the lowest common multiple of 749,731,430,602 is 5475190.
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.
749 x 731 x 430 x 602 = 141730768340
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.
749 : 1, 7, 107, 749
731 : 1, 17, 43, 731
430 : 1, 2, 5, 10, 43, 86, 215, 430
602 : 1, 2, 7, 14, 43, 86, 301, 602
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,731,430,602, is 1.
Now, the common factors can be found like this.
749:7x 107
731:17x 43
430:2x 5x 43
602:2x 7x 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 7x 43x 43 = 25886
Therefore, the value for common factors is 25886.
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 = 141730768340/(1x25886)
LCM = 141730768340/25886
LCM = 5475190
Thus, we can understand that the LCM of 749,731,430,602 is 5475190.
