Given numbers are 711,542,553,821
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 711,542,553,821 is 2214675414.
Find LCM of 711,542,553,821 with Prime Factorization
79 | 711, 542, 553, 821 |
9, 542, 7, 821 |
Multiply the prime numbers at the bottom and the left side.
79 x 9 x 542 x 7 x 821 = 2214675414
Therefore, the lowest common multiple of 711,542,553,821 is 2214675414.
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.
711 x 542 x 553 x 821 = 174959357706
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.
711 : 1, 3, 9, 79, 237, 711
542 : 1, 2, 271, 542
553 : 1, 7, 79, 553
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 711,542,553,821, is 1.
Now, the common factors can be found like this.
711:3x 3x 79
542:2x 271
553:7x 79
821:821
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
79 = 79
Therefore, the value for common factors is 79.
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 = 174959357706/(1x79)
LCM = 174959357706/79
LCM = 2214675414
Thus, we can understand that the LCM of 711,542,553,821 is 2214675414.
