Given numbers are 786,552,782,749
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 786,552,782,749 is 920748696.
Find LCM of 786,552,782,749 with Prime Factorization
2 | 786, 552, 782, 749 |
3 | 393, 276, 391, 749 |
23 | 131, 92, 391, 749 |
131, 4, 17, 749 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 131 x 4 x 17 x 749 = 920748696
Therefore, the lowest common multiple of 786,552,782,749 is 920748696.
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.
786 x 552 x 782 x 749 = 254126640096
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.
786 : 1, 2, 3, 6, 131, 262, 393, 786
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
782 : 1, 2, 17, 23, 34, 46, 391, 782
749 : 1, 7, 107, 749
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,552,782,749, is 1.
Now, the common factors can be found like this.
786:2x 3x 131
552:2x 2x 2x 3x 23
782:2x 17x 23
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.
2x 2x 3x 23 = 276
Therefore, the value for common factors is 276.
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 = 254126640096/(1x276)
LCM = 254126640096/276
LCM = 920748696
Thus, we can understand that the LCM of 786,552,782,749 is 920748696.
