Given numbers are 628,756,532,761
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 628,756,532,761 is 1716167628.
Find LCM of 628,756,532,761 with Prime Factorization
2 | 628, 756, 532, 761 |
2 | 314, 378, 266, 761 |
7 | 157, 189, 133, 761 |
157, 27, 19, 761 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 157 x 27 x 19 x 761 = 1716167628
Therefore, the lowest common multiple of 628,756,532,761 is 1716167628.
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.
628 x 756 x 532 x 761 = 192210774336
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.
628 : 1, 2, 4, 157, 314, 628
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
761 : 1, 761
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,756,532,761, is 1.
Now, the common factors can be found like this.
628:2x 2x 157
756:2x 2x 3x 3x 3x 7
532:2x 2x 7x 19
761:761
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 2x 7 = 112
Therefore, the value for common factors is 112.
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 = 192210774336/(1x112)
LCM = 192210774336/112
LCM = 1716167628
Thus, we can understand that the LCM of 628,756,532,761 is 1716167628.
