HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 671, 473, 622 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 671, 473, 622 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 671, 473, 622 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 671, 473, 622 is 1.

HCF(671, 473, 622) = 1

Highest common factor (HCF) of 671, 473, 622 is 1.

Highest Common Factor of 671,473,622 using Euclid's algorithm

Highest Common Factor of 671,473,622 is 1

Step 1: Since 671 > 473, we apply the division lemma to 671 and 473, to get

671 = 473 x 1 + 198

Step 2: Since the reminder 473 ≠ 0, we apply division lemma to 198 and 473, to get

473 = 198 x 2 + 77

Step 3: We consider the new divisor 198 and the new remainder 77, and apply the division lemma to get

198 = 77 x 2 + 44

We consider the new divisor 77 and the new remainder 44,and apply the division lemma to get

77 = 44 x 1 + 33

We consider the new divisor 44 and the new remainder 33,and apply the division lemma to get

44 = 33 x 1 + 11

We consider the new divisor 33 and the new remainder 11,and apply the division lemma to get

33 = 11 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 671 and 473 is 11

Notice that 11 = HCF(33,11) = HCF(44,33) = HCF(77,44) = HCF(198,77) = HCF(473,198) = HCF(671,473) .

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

Step 1: Since 622 > 11, we apply the division lemma to 622 and 11, to get

622 = 11 x 56 + 6

Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 6 and 11, to get

11 = 6 x 1 + 5

Step 3: We consider the new divisor 6 and the new remainder 5, and apply the division lemma to get

6 = 5 x 1 + 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 11 and 622 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(622,11) .
