HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 970, 798, 308 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 970, 798, 308 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 970, 798, 308 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 970, 798, 308 is 2.
HCF(970, 798, 308) = 2
HCF of 970, 798, 308 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 970, 798, 308 is 2.
Highest Common Factor of 970,798,308 is 2
Step 1: Since 970 > 798, we apply the division lemma to 970 and 798, to get
970 = 798 x 1 + 172
Step 2: Since the reminder 798 ≠ 0, we apply division lemma to 172 and 798, to get
798 = 172 x 4 + 110
Step 3: We consider the new divisor 172 and the new remainder 110, and apply the division lemma to get
172 = 110 x 1 + 62
We consider the new divisor 110 and the new remainder 62,and apply the division lemma to get
110 = 62 x 1 + 48
We consider the new divisor 62 and the new remainder 48,and apply the division lemma to get
62 = 48 x 1 + 14
We consider the new divisor 48 and the new remainder 14,and apply the division lemma to get
48 = 14 x 3 + 6
We consider the new divisor 14 and the new remainder 6,and apply the division lemma to get
14 = 6 x 2 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 970 and 798 is 2
Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(48,14) = HCF(62,48) = HCF(110,62) = HCF(172,110) = HCF(798,172) = HCF(970,798) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 308 > 2, we apply the division lemma to 308 and 2, to get
308 = 2 x 154 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 308 is 2
Notice that 2 = HCF(308,2) .
