Given numbers are 257,824,620,124,278
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 257,824,620,124,278 is 4562541560.
Find LCM of 257,824,620,124,278 with Prime Factorization
2 | 257, 824, 620, 124, 278 |
2 | 257, 412, 310, 62, 139 |
31 | 257, 206, 155, 31, 139 |
257, 206, 5, 1, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 31 x 257 x 206 x 5 x 1 x 139 = 4562541560
Therefore, the lowest common multiple of 257,824,620,124,278 is 4562541560.
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.
257 x 824 x 620 x 124 x 278 = 4526041227520
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.
257 : 1, 257
824 : 1, 2, 4, 8, 103, 206, 412, 824
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
124 : 1, 2, 4, 31, 62, 124
278 : 1, 2, 139, 278
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,824,620,124,278, is 1.
Now, the common factors can be found like this.
257:257
824:2x 2x 2x 103
620:2x 2x 5x 31
124:2x 2x 31
278:2x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2x 31 = 992
Therefore, the value for common factors is 992.
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 = 4526041227520/(1x992)
LCM = 4526041227520/992
LCM = 4562541560
Thus, we can understand that the LCM of 257,824,620,124,278 is 4562541560.
