Given numbers are 248,507,679,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 248,507,679,221 is 1451370648.
Find LCM of 248,507,679,221 with Prime Factorization
13 | 248, 507, 679, 221 |
248, 39, 679, 17 |
Multiply the prime numbers at the bottom and the left side.
13 x 248 x 39 x 679 x 17 = 1451370648
Therefore, the lowest common multiple of 248,507,679,221 is 1451370648.
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.
248 x 507 x 679 x 221 = 18867818424
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.
248 : 1, 2, 4, 8, 31, 62, 124, 248
507 : 1, 3, 13, 39, 169, 507
679 : 1, 7, 97, 679
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 248,507,679,221, is 1.
Now, the common factors can be found like this.
248:2x 2x 2x 31
507:3x 13x 13
679:7x 97
221:13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 18867818424/(1x13)
LCM = 18867818424/13
LCM = 1451370648
Thus, we can understand that the LCM of 248,507,679,221 is 1451370648.
