Given numbers are 771,562,781,872
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 771,562,781,872 is 147546263832.
Find LCM of 771,562,781,872 with Prime Factorization
2 | 771, 562, 781, 872 |
771, 281, 781, 436 |
Multiply the prime numbers at the bottom and the left side.
2 x 771 x 281 x 781 x 436 = 147546263832
Therefore, the lowest common multiple of 771,562,781,872 is 147546263832.
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.
771 x 562 x 781 x 872 = 295092527664
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.
771 : 1, 3, 257, 771
562 : 1, 2, 281, 562
781 : 1, 11, 71, 781
872 : 1, 2, 4, 8, 109, 218, 436, 872
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,562,781,872, is 1.
Now, the common factors can be found like this.
771:3x 257
562:2x 281
781:11x 71
872:2x 2x 2x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 295092527664/(1x2)
LCM = 295092527664/2
LCM = 147546263832
Thus, we can understand that the LCM of 771,562,781,872 is 147546263832.
