The LCM of 621,943,146,820 is 37173060.

Find LCM of 621,943,146,820 with Prime Factorization


2 621, 943, 146, 820
23 621, 943, 73, 410
41 27, 41, 73, 410
27, 1, 73, 10

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

2 x 23 x 41 x 27 x 1 x 73 x 10 = 37173060

Therefore, the lowest common multiple of 621,943,146,820 is 37173060.

LCM Formula to Find Lowest Common Multiple of 621,943,146,820

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.

621 x 943 x 146 x 820 = 70108391160

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.

621 : 1, 3, 9, 23, 27, 69, 207, 621

943 : 1, 23, 41, 943

146 : 1, 2, 73, 146

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,943,146,820, is 1.

Now, the common factors can be found like this.

621:3x 3x 3x 23

943:23x 41

146:2x 73

820:2x 2x 5x 41

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

2x 23x 41 = 1886

Therefore, the value for common factors is 1886.

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 = 70108391160/(1x1886)

LCM = 70108391160/1886

LCM = 37173060

Thus, we can understand that the LCM of 621,943,146,820 is 37173060.
