HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 921, 563, 394 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 921, 563, 394 is 1 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 921, 563, 394 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 921, 563, 394 is 1.

HCF(921, 563, 394) = 1

HCF of 921, 563, 394 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 921, 563, 394 is 1.

Highest Common Factor of 921,563,394 using Euclid's algorithm

Highest Common Factor of 921,563,394 is 1

Step 1: Since 921 > 563, we apply the division lemma to 921 and 563, to get

921 = 563 x 1 + 358

Step 2: Since the reminder 563 ≠ 0, we apply division lemma to 358 and 563, to get

563 = 358 x 1 + 205

Step 3: We consider the new divisor 358 and the new remainder 205, and apply the division lemma to get

358 = 205 x 1 + 153

We consider the new divisor 205 and the new remainder 153,and apply the division lemma to get

205 = 153 x 1 + 52

We consider the new divisor 153 and the new remainder 52,and apply the division lemma to get

153 = 52 x 2 + 49

We consider the new divisor 52 and the new remainder 49,and apply the division lemma to get

52 = 49 x 1 + 3

We consider the new divisor 49 and the new remainder 3,and apply the division lemma to get

49 = 3 x 16 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 921 and 563 is 1

Notice that 1 = HCF(3,1) = HCF(49,3) = HCF(52,49) = HCF(153,52) = HCF(205,153) = HCF(358,205) = HCF(563,358) = HCF(921,563) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 394 > 1, we apply the division lemma to 394 and 1, to get

394 = 1 x 394 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 394 is 1

Notice that 1 = HCF(394,1) .
