HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 384, 668 i.e. 4 the largest integer that leaves a remainder zero for all numbers.

HCF of 384, 668 is 4 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 384, 668 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 384, 668 is 4.

HCF(384, 668) = 4

HCF of 384, 668 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 384, 668 is 4.

Highest Common Factor of 384,668 using Euclid's algorithm

Highest Common Factor of 384,668 is 4

Step 1: Since 668 > 384, we apply the division lemma to 668 and 384, to get

668 = 384 x 1 + 284

Step 2: Since the reminder 384 ≠ 0, we apply division lemma to 284 and 384, to get

384 = 284 x 1 + 100

Step 3: We consider the new divisor 284 and the new remainder 100, and apply the division lemma to get

284 = 100 x 2 + 84

We consider the new divisor 100 and the new remainder 84,and apply the division lemma to get

100 = 84 x 1 + 16

We consider the new divisor 84 and the new remainder 16,and apply the division lemma to get

84 = 16 x 5 + 4

We consider the new divisor 16 and the new remainder 4,and apply the division lemma to get

16 = 4 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 384 and 668 is 4

Notice that 4 = HCF(16,4) = HCF(84,16) = HCF(100,84) = HCF(284,100) = HCF(384,284) = HCF(668,384) .
