Calculate the LCM of 741,640,213,978

Given numbers are 741,640,213,978

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

The LCM of 741,640,213,978 is 5488379520.

Find LCM of 741,640,213,978 with Prime Factorization


2 741, 640, 213, 978
3 741, 320, 213, 489
247, 320, 71, 163

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

2 x 3 x 247 x 320 x 71 x 163 = 5488379520

Therefore, the lowest common multiple of 741,640,213,978 is 5488379520.

LCM Formula to Find Lowest Common Multiple of 741,640,213,978

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.

741 x 640 x 213 x 978 = 98790831360

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.

741 : 1, 3, 13, 19, 39, 57, 247, 741

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

213 : 1, 3, 71, 213

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,640,213,978, is 1.

Now, the common factors can be found like this.

741:3x 13x 19

640:2x 2x 2x 2x 2x 2x 2x 5

213:3x 71

978:2x 3x 163

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 98790831360/(1x18)

LCM = 98790831360/18

LCM = 5488379520

Thus, we can understand that the LCM of 741,640,213,978 is 5488379520.
