Given numbers are 788,839,654,557
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 788,839,654,557 is 120417921348.
Find LCM of 788,839,654,557 with Prime Factorization
2 | 788, 839, 654, 557 |
394, 839, 327, 557 |
Multiply the prime numbers at the bottom and the left side.
2 x 394 x 839 x 327 x 557 = 120417921348
Therefore, the lowest common multiple of 788,839,654,557 is 120417921348.
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.
788 x 839 x 654 x 557 = 240835842696
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.
788 : 1, 2, 4, 197, 394, 788
839 : 1, 839
654 : 1, 2, 3, 6, 109, 218, 327, 654
557 : 1, 557
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,839,654,557, is 1.
Now, the common factors can be found like this.
788:2x 2x 197
839:839
654:2x 3x 109
557:557
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 240835842696/(1x2)
LCM = 240835842696/2
LCM = 120417921348
Thus, we can understand that the LCM of 788,839,654,557 is 120417921348.
