Given numbers are 782,749,534,124,388
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 782,749,534,124,388 is 940509649884.
Find LCM of 782,749,534,124,388 with Prime Factorization
2 | 782, 749, 534, 124, 388 |
2 | 391, 749, 267, 62, 194 |
391, 749, 267, 31, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 391 x 749 x 267 x 31 x 97 = 940509649884
Therefore, the lowest common multiple of 782,749,534,124,388 is 940509649884.
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.
782 x 749 x 534 x 124 x 388 = 15048154398144
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
749 : 1, 7, 107, 749
534 : 1, 2, 3, 6, 89, 178, 267, 534
124 : 1, 2, 4, 31, 62, 124
388 : 1, 2, 4, 97, 194, 388
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,749,534,124,388, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
749:7x 107
534:2x 3x 89
124:2x 2x 31
388:2x 2x 97
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 2x 2 = 16
Therefore, the value for common factors is 16.
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 = 15048154398144/(1x16)
LCM = 15048154398144/16
LCM = 940509649884
Thus, we can understand that the LCM of 782,749,534,124,388 is 940509649884.
