Calculate the LCM of 978,578,875,180,402

Given numbers are 978,578,875,180,402

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

The LCM of 978,578,875,180,402 is 99419323500.

Find LCM of 978,578,875,180,402 with Prime Factorization


2 978, 578, 875, 180, 402
3 489, 289, 875, 90, 201
5 163, 289, 875, 30, 67
163, 289, 175, 6, 67

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

2 x 3 x 5 x 163 x 289 x 175 x 6 x 67 = 99419323500

Therefore, the lowest common multiple of 978,578,875,180,402 is 99419323500.

LCM Formula to Find Lowest Common Multiple of 978,578,875,180,402

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.

978 x 578 x 875 x 180 x 402 = 35790956460000

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.

978 : 1, 2, 3, 6, 163, 326, 489, 978

578 : 1, 2, 17, 34, 289, 578

875 : 1, 5, 7, 25, 35, 125, 175, 875

180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

402 : 1, 2, 3, 6, 67, 134, 201, 402

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,578,875,180,402, is 1.

Now, the common factors can be found like this.

978:2x 3x 163

578:2x 17x 17

875:5x 5x 5x 7

180:2x 2x 3x 3x 5

402:2x 3x 67

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 3x 3x 5 = 360

Therefore, the value for common factors is 360.

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 = 35790956460000/(1x360)

LCM = 35790956460000/360

LCM = 99419323500

Thus, we can understand that the LCM of 978,578,875,180,402 is 99419323500.
