Given numbers are 491,728,655,465,965
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 491,728,655,465,965 is 4202371369560.
Find LCM of 491,728,655,465,965 with Prime Factorization
5 | 491, 728, 655, 465, 965 |
491, 728, 131, 93, 193 |
Multiply the prime numbers at the bottom and the left side.
5 x 491 x 728 x 131 x 93 x 193 = 4202371369560
Therefore, the lowest common multiple of 491,728,655,465,965 is 4202371369560.
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.
491 x 728 x 655 x 465 x 965 = 105059284239000
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.
491 : 1, 491
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
655 : 1, 5, 131, 655
465 : 1, 3, 5, 15, 31, 93, 155, 465
965 : 1, 5, 193, 965
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 491,728,655,465,965, is 1.
Now, the common factors can be found like this.
491:491
728:2x 2x 2x 7x 13
655:5x 131
465:3x 5x 31
965:5x 193
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5 = 25
Therefore, the value for common factors is 25.
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 = 105059284239000/(1x25)
LCM = 105059284239000/25
LCM = 4202371369560
Thus, we can understand that the LCM of 491,728,655,465,965 is 4202371369560.
