Calculate the LCM of 7,343,616,245

Given numbers are 7,343,616,245

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 7,343,616,245 is 150920.

Find LCM of 7,343,616,245 with Prime Factorization


7 7, 343, 616, 245
7 1, 49, 88, 35
1, 7, 88, 5

Multiply the prime numbers at the bottom and the left side.

7 x 7 x 1 x 7 x 88 x 5 = 150920

Therefore, the lowest common multiple of 7,343,616,245 is 150920.

LCM Formula to Find Lowest Common Multiple of 7,343,616,245

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.

7 x 343 x 616 x 245 = 362358920

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.

7 : 1, 7

343 : 1, 7, 49, 343

616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616

245 : 1, 5, 7, 35, 49, 245

7 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,343,616,245, is 7.

Now, the common factors can be found like this.

7:7

343:7x 7x 7

616:2x 2x 2x 7x 11

245:5x 7x 7

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

7x 7x 7 = 343

Therefore, the value for common factors is 343.

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 = 362358920/(7x343)

LCM = 362358920/2401

LCM = 150920

Thus, we can understand that the LCM of 7,343,616,245 is 150920.
