Given numbers are 843,840,211,421,705
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 843,840,211,421,705 is 985480454280.
Find LCM of 843,840,211,421,705 with Prime Factorization
3 | 843, 840, 211, 421, 705 |
5 | 281, 280, 211, 421, 235 |
281, 56, 211, 421, 47 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 281 x 56 x 211 x 421 x 47 = 985480454280
Therefore, the lowest common multiple of 843,840,211,421,705 is 985480454280.
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.
843 x 840 x 211 x 421 x 705 = 44346620442600
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.
843 : 1, 3, 281, 843
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
211 : 1, 211
421 : 1, 421
705 : 1, 3, 5, 15, 47, 141, 235, 705
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,840,211,421,705, is 1.
Now, the common factors can be found like this.
843:3x 281
840:2x 2x 2x 3x 5x 7
211:211
421:421
705:3x 5x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5 = 45
Therefore, the value for common factors is 45.
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 = 44346620442600/(1x45)
LCM = 44346620442600/45
LCM = 985480454280
Thus, we can understand that the LCM of 843,840,211,421,705 is 985480454280.
