HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 945, 206, 681 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 945, 206, 681 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 945, 206, 681 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 945, 206, 681 is 1.

HCF(945, 206, 681) = 1

Highest common factor (HCF) of 945, 206, 681 is 1.

Highest Common Factor of 945,206,681 using Euclid's algorithm

Highest Common Factor of 945,206,681 is 1

Step 1: Since 945 > 206, we apply the division lemma to 945 and 206, to get

945 = 206 x 4 + 121

Step 2: Since the reminder 206 ≠ 0, we apply division lemma to 121 and 206, to get

206 = 121 x 1 + 85

Step 3: We consider the new divisor 121 and the new remainder 85, and apply the division lemma to get

121 = 85 x 1 + 36

We consider the new divisor 85 and the new remainder 36,and apply the division lemma to get

85 = 36 x 2 + 13

We consider the new divisor 36 and the new remainder 13,and apply the division lemma to get

36 = 13 x 2 + 10

We consider the new divisor 13 and the new remainder 10,and apply the division lemma to get

13 = 10 x 1 + 3

We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get

10 = 3 x 3 + 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 945 and 206 is 1

Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(13,10) = HCF(36,13) = HCF(85,36) = HCF(121,85) = HCF(206,121) = HCF(945,206) .

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

Step 1: Since 681 > 1, we apply the division lemma to 681 and 1, to get

681 = 1 x 681 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 681 is 1

Notice that 1 = HCF(681,1) .
