HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 994, 788, 772 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 994, 788, 772 is 2 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 994, 788, 772 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 994, 788, 772 is 2.
HCF(994, 788, 772) = 2
HCF of 994, 788, 772 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 994, 788, 772 is 2.
Highest Common Factor of 994,788,772 is 2
Step 1: Since 994 > 788, we apply the division lemma to 994 and 788, to get
994 = 788 x 1 + 206
Step 2: Since the reminder 788 ≠ 0, we apply division lemma to 206 and 788, to get
788 = 206 x 3 + 170
Step 3: We consider the new divisor 206 and the new remainder 170, and apply the division lemma to get
206 = 170 x 1 + 36
We consider the new divisor 170 and the new remainder 36,and apply the division lemma to get
170 = 36 x 4 + 26
We consider the new divisor 36 and the new remainder 26,and apply the division lemma to get
36 = 26 x 1 + 10
We consider the new divisor 26 and the new remainder 10,and apply the division lemma to get
26 = 10 x 2 + 6
We consider the new divisor 10 and the new remainder 6,and apply the division lemma to get
10 = 6 x 1 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 994 and 788 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(26,10) = HCF(36,26) = HCF(170,36) = HCF(206,170) = HCF(788,206) = HCF(994,788) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 772 > 2, we apply the division lemma to 772 and 2, to get
772 = 2 x 386 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 772 is 2
Notice that 2 = HCF(772,2) .
