Calculate the LCM of 728,603,406,668,970

Given numbers are 728,603,406,668,970

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

The LCM of 728,603,406,668,970 is 1031109763320.

Find LCM of 728,603,406,668,970 with Prime Factorization


2 728, 603, 406, 668, 970
2 364, 603, 203, 334, 485
7 182, 603, 203, 167, 485
26, 603, 29, 167, 485

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

2 x 2 x 7 x 26 x 603 x 29 x 167 x 485 = 1031109763320

Therefore, the lowest common multiple of 728,603,406,668,970 is 1031109763320.

LCM Formula to Find Lowest Common Multiple of 728,603,406,668,970

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.

728 x 603 x 406 x 668 x 970 = 115484293491840

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.

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

603 : 1, 3, 9, 67, 201, 603

406 : 1, 2, 7, 14, 29, 58, 203, 406

668 : 1, 2, 4, 167, 334, 668

970 : 1, 2, 5, 10, 97, 194, 485, 970

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,603,406,668,970, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

603:3x 3x 67

406:2x 7x 29

668:2x 2x 167

970:2x 5x 97

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 7 = 112

Therefore, the value for common factors is 112.

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 = 115484293491840/(1x112)

LCM = 115484293491840/112

LCM = 1031109763320

Thus, we can understand that the LCM of 728,603,406,668,970 is 1031109763320.
