HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 605, 990, 622, 94 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 605, 990, 622, 94 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 605, 990, 622, 94 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 605, 990, 622, 94 is 1.

HCF(605, 990, 622, 94) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 605, 990, 622, 94 is 1.

Highest Common Factor of 605,990,622,94 using Euclid's algorithm

Highest Common Factor of 605,990,622,94 is 1

Step 1: Since 990 > 605, we apply the division lemma to 990 and 605, to get

990 = 605 x 1 + 385

Step 2: Since the reminder 605 ≠ 0, we apply division lemma to 385 and 605, to get

605 = 385 x 1 + 220

Step 3: We consider the new divisor 385 and the new remainder 220, and apply the division lemma to get

385 = 220 x 1 + 165

We consider the new divisor 220 and the new remainder 165,and apply the division lemma to get

220 = 165 x 1 + 55

We consider the new divisor 165 and the new remainder 55,and apply the division lemma to get

165 = 55 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 55, the HCF of 605 and 990 is 55

Notice that 55 = HCF(165,55) = HCF(220,165) = HCF(385,220) = HCF(605,385) = HCF(990,605) .


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

Step 1: Since 622 > 55, we apply the division lemma to 622 and 55, to get

622 = 55 x 11 + 17

Step 2: Since the reminder 55 ≠ 0, we apply division lemma to 17 and 55, to get

55 = 17 x 3 + 4

Step 3: We consider the new divisor 17 and the new remainder 4, and apply the division lemma to get

17 = 4 x 4 + 1

We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 55 and 622 is 1

Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(55,17) = HCF(622,55) .


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

Step 1: Since 94 > 1, we apply the division lemma to 94 and 1, to get

94 = 1 x 94 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 94 is 1

Notice that 1 = HCF(94,1) .
