Calculate the LCM of 762,824,142,821

Given numbers are 762,824,142,821

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

The LCM of 762,824,142,821 is 18300109704.

Find LCM of 762,824,142,821 with Prime Factorization


2 762, 824, 142, 821
381, 412, 71, 821

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

2 x 381 x 412 x 71 x 821 = 18300109704

Therefore, the lowest common multiple of 762,824,142,821 is 18300109704.

LCM Formula to Find Lowest Common Multiple of 762,824,142,821

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.

762 x 824 x 142 x 821 = 73200438816

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.

762 : 1, 2, 3, 6, 127, 254, 381, 762

824 : 1, 2, 4, 8, 103, 206, 412, 824

142 : 1, 2, 71, 142

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 762,824,142,821, is 1.

Now, the common factors can be found like this.

762:2x 3x 127

824:2x 2x 2x 103

142:2x 71

821:821

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 73200438816/(1x4)

LCM = 73200438816/4

LCM = 18300109704

Thus, we can understand that the LCM of 762,824,142,821 is 18300109704.
