Calculate the LCM of 786,573,390,436,971

Given numbers are 786,573,390,436,971

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

The LCM of 786,573,390,436,971 is 2065594142820.

Find LCM of 786,573,390,436,971 with Prime Factorization


2 786, 573, 390, 436, 971
3 393, 573, 195, 218, 971
131, 191, 65, 218, 971

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

2 x 3 x 131 x 191 x 65 x 218 x 971 = 2065594142820

Therefore, the lowest common multiple of 786,573,390,436,971 is 2065594142820.

LCM Formula to Find Lowest Common Multiple of 786,573,390,436,971

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.

786 x 573 x 390 x 436 x 971 = 74361389141520

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.

786 : 1, 2, 3, 6, 131, 262, 393, 786

573 : 1, 3, 191, 573

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

436 : 1, 2, 4, 109, 218, 436

971 : 1, 971

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,573,390,436,971, is 1.

Now, the common factors can be found like this.

786:2x 3x 131

573:3x 191

390:2x 3x 5x 13

436:2x 2x 109

971:971

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 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 74361389141520/(1x36)

LCM = 74361389141520/36

LCM = 2065594142820

Thus, we can understand that the LCM of 786,573,390,436,971 is 2065594142820.
