Given numbers are 893,247,978,434
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 893,247,978,434 is 2463731634.
Find LCM of 893,247,978,434 with Prime Factorization
2 | 893, 247, 978, 434 |
19 | 893, 247, 489, 217 |
47, 13, 489, 217 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 47 x 13 x 489 x 217 = 2463731634
Therefore, the lowest common multiple of 893,247,978,434 is 2463731634.
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.
893 x 247 x 978 x 434 = 93621802092
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.
893 : 1, 19, 47, 893
247 : 1, 13, 19, 247
978 : 1, 2, 3, 6, 163, 326, 489, 978
434 : 1, 2, 7, 14, 31, 62, 217, 434
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 893,247,978,434, is 1.
Now, the common factors can be found like this.
893:19x 47
247:13x 19
978:2x 3x 163
434:2x 7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 19 = 38
Therefore, the value for common factors is 38.
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 = 93621802092/(1x38)
LCM = 93621802092/38
LCM = 2463731634
Thus, we can understand that the LCM of 893,247,978,434 is 2463731634.
