Calculate the LCM of 698,900,850,221

Given numbers are 698,900,850,221

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

The LCM of 698,900,850,221 is 69416100.

Find LCM of 698,900,850,221 with Prime Factorization


2 698, 900, 850, 221
5 349, 450, 425, 221
5 349, 90, 85, 221
17 349, 18, 17, 221
349, 18, 1, 13

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

2 x 5 x 5 x 17 x 349 x 18 x 1 x 13 = 69416100

Therefore, the lowest common multiple of 698,900,850,221 is 69416100.

LCM Formula to Find Lowest Common Multiple of 698,900,850,221

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.

698 x 900 x 850 x 221 = 118007370000

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.

698 : 1, 2, 349, 698

900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900

850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,900,850,221, is 1.

Now, the common factors can be found like this.

698:2x 349

900:2x 2x 3x 3x 5x 5

850:2x 5x 5x 17

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.

2x 2x 5x 5x 17 = 1700

Therefore, the value for common factors is 1700.

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 = 118007370000/(1x1700)

LCM = 118007370000/1700

LCM = 69416100

Thus, we can understand that the LCM of 698,900,850,221 is 69416100.
