HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 622, 845 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 622, 845 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 622, 845 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 622, 845 is 1.

HCF(622, 845) = 1

Highest common factor (HCF) of 622, 845 is 1.

Highest Common Factor of 622,845 using Euclid's algorithm

Highest Common Factor of 622,845 is 1

Step 1: Since 845 > 622, we apply the division lemma to 845 and 622, to get

845 = 622 x 1 + 223

Step 2: Since the reminder 622 ≠ 0, we apply division lemma to 223 and 622, to get

622 = 223 x 2 + 176

Step 3: We consider the new divisor 223 and the new remainder 176, and apply the division lemma to get

223 = 176 x 1 + 47

We consider the new divisor 176 and the new remainder 47,and apply the division lemma to get

176 = 47 x 3 + 35

We consider the new divisor 47 and the new remainder 35,and apply the division lemma to get

47 = 35 x 1 + 12

We consider the new divisor 35 and the new remainder 12,and apply the division lemma to get

35 = 12 x 2 + 11

We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get

12 = 11 x 1 + 1

We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get

11 = 1 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 622 and 845 is 1

Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(35,12) = HCF(47,35) = HCF(176,47) = HCF(223,176) = HCF(622,223) = HCF(845,622) .
