HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 999, 622, 968 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 999, 622, 968 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 999, 622, 968 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 999, 622, 968 is 1.

HCF(999, 622, 968) = 1

HCF of 999, 622, 968 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 999, 622, 968 is 1.

Highest Common Factor of 999,622,968 using Euclid's algorithm

Highest Common Factor of 999,622,968 is 1

Step 1: Since 999 > 622, we apply the division lemma to 999 and 622, to get

999 = 622 x 1 + 377

Step 2: Since the reminder 622 ≠ 0, we apply division lemma to 377 and 622, to get

622 = 377 x 1 + 245

Step 3: We consider the new divisor 377 and the new remainder 245, and apply the division lemma to get

377 = 245 x 1 + 132

We consider the new divisor 245 and the new remainder 132,and apply the division lemma to get

245 = 132 x 1 + 113

We consider the new divisor 132 and the new remainder 113,and apply the division lemma to get

132 = 113 x 1 + 19

We consider the new divisor 113 and the new remainder 19,and apply the division lemma to get

113 = 19 x 5 + 18

We consider the new divisor 19 and the new remainder 18,and apply the division lemma to get

19 = 18 x 1 + 1

We consider the new divisor 18 and the new remainder 1,and apply the division lemma to get

18 = 1 x 18 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 999 and 622 is 1

Notice that 1 = HCF(18,1) = HCF(19,18) = HCF(113,19) = HCF(132,113) = HCF(245,132) = HCF(377,245) = HCF(622,377) = HCF(999,622) .

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

Step 1: Since 968 > 1, we apply the division lemma to 968 and 1, to get

968 = 1 x 968 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 968 is 1

Notice that 1 = HCF(968,1) .
