Given numbers are 721,347,561,347
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,347,561,347 is 140354907.
Find LCM of 721,347,561,347 with Prime Factorization
347 | 721, 347, 561, 347 |
721, 1, 561, 1 |
Multiply the prime numbers at the bottom and the left side.
347 x 721 x 1 x 561 x 1 = 140354907
Therefore, the lowest common multiple of 721,347,561,347 is 140354907.
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.
721 x 347 x 561 x 347 = 48703152729
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.
721 : 1, 7, 103, 721
347 : 1, 347
561 : 1, 3, 11, 17, 33, 51, 187, 561
347 : 1, 347
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,347,561,347, is 1.
Now, the common factors can be found like this.
721:7x 103
347:347
561:3x 11x 17
347:347
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
347 = 347
Therefore, the value for common factors is 347.
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 = 48703152729/(1x347)
LCM = 48703152729/347
LCM = 140354907
Thus, we can understand that the LCM of 721,347,561,347 is 140354907.
