Given numbers are 778,620,935,279
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 778,620,935,279 is 405905940.
Find LCM of 778,620,935,279 with Prime Factorization
2 | 778, 620, 935, 279 |
5 | 389, 310, 935, 279 |
31 | 389, 62, 187, 279 |
389, 2, 187, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 31 x 389 x 2 x 187 x 9 = 405905940
Therefore, the lowest common multiple of 778,620,935,279 is 405905940.
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.
778 x 620 x 935 x 279 = 125830841400
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.
778 : 1, 2, 389, 778
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
935 : 1, 5, 11, 17, 55, 85, 187, 935
279 : 1, 3, 9, 31, 93, 279
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,620,935,279, is 1.
Now, the common factors can be found like this.
778:2x 389
620:2x 2x 5x 31
935:5x 11x 17
279:3x 3x 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 5x 31 = 310
Therefore, the value for common factors is 310.
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 = 125830841400/(1x310)
LCM = 125830841400/310
LCM = 405905940
Thus, we can understand that the LCM of 778,620,935,279 is 405905940.
