HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7226, 8723, 68991 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 7226, 8723, 68991 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 7226, 8723, 68991 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 7226, 8723, 68991 is 1.

HCF(7226, 8723, 68991) = 1

Highest common factor (HCF) of 7226, 8723, 68991 is 1.

Highest Common Factor of 7226,8723,68991 using Euclid's algorithm

Highest Common Factor of 7226,8723,68991 is 1

Step 1: Since 8723 > 7226, we apply the division lemma to 8723 and 7226, to get

8723 = 7226 x 1 + 1497

Step 2: Since the reminder 7226 ≠ 0, we apply division lemma to 1497 and 7226, to get

7226 = 1497 x 4 + 1238

Step 3: We consider the new divisor 1497 and the new remainder 1238, and apply the division lemma to get

1497 = 1238 x 1 + 259

We consider the new divisor 1238 and the new remainder 259,and apply the division lemma to get

1238 = 259 x 4 + 202

We consider the new divisor 259 and the new remainder 202,and apply the division lemma to get

259 = 202 x 1 + 57

We consider the new divisor 202 and the new remainder 57,and apply the division lemma to get

202 = 57 x 3 + 31

We consider the new divisor 57 and the new remainder 31,and apply the division lemma to get

57 = 31 x 1 + 26

We consider the new divisor 31 and the new remainder 26,and apply the division lemma to get

31 = 26 x 1 + 5

We consider the new divisor 26 and the new remainder 5,and apply the division lemma to get

26 = 5 x 5 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7226 and 8723 is 1

Notice that 1 = HCF(5,1) = HCF(26,5) = HCF(31,26) = HCF(57,31) = HCF(202,57) = HCF(259,202) = HCF(1238,259) = HCF(1497,1238) = HCF(7226,1497) = HCF(8723,7226) .

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

Step 1: Since 68991 > 1, we apply the division lemma to 68991 and 1, to get

68991 = 1 x 68991 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 68991 is 1

Notice that 1 = HCF(68991,1) .
