Given numbers are 669,415,678,749
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 669,415,678,749 is 46996386990.
Find LCM of 669,415,678,749 with Prime Factorization
3 | 669, 415, 678, 749 |
223, 415, 226, 749 |
Multiply the prime numbers at the bottom and the left side.
3 x 223 x 415 x 226 x 749 = 46996386990
Therefore, the lowest common multiple of 669,415,678,749 is 46996386990.
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.
669 x 415 x 678 x 749 = 140989160970
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.
669 : 1, 3, 223, 669
415 : 1, 5, 83, 415
678 : 1, 2, 3, 6, 113, 226, 339, 678
749 : 1, 7, 107, 749
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,415,678,749, is 1.
Now, the common factors can be found like this.
669:3x 223
415:5x 83
678:2x 3x 113
749:7x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 140989160970/(1x3)
LCM = 140989160970/3
LCM = 46996386990
Thus, we can understand that the LCM of 669,415,678,749 is 46996386990.
