Given numbers are 279,868,419,603
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 279,868,419,603 is 219306276.
Find LCM of 279,868,419,603 with Prime Factorization
3 | 279, 868, 419, 603 |
3 | 93, 868, 419, 201 |
31 | 31, 868, 419, 67 |
1, 28, 419, 67 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 31 x 1 x 28 x 419 x 67 = 219306276
Therefore, the lowest common multiple of 279,868,419,603 is 219306276.
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.
279 x 868 x 419 x 603 = 61186451004
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.
279 : 1, 3, 9, 31, 93, 279
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
419 : 1, 419
603 : 1, 3, 9, 67, 201, 603
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 279,868,419,603, is 1.
Now, the common factors can be found like this.
279:3x 3x 31
868:2x 2x 7x 31
419:419
603:3x 3x 67
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 31 = 279
Therefore, the value for common factors is 279.
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 = 61186451004/(1x279)
LCM = 61186451004/279
LCM = 219306276
Thus, we can understand that the LCM of 279,868,419,603 is 219306276.
