HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 794, 7470 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 794, 7470 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 794, 7470 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 794, 7470 is 2.
HCF(794, 7470) = 2
HCF of 794, 7470 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 794, 7470 is 2.
Highest Common Factor of 794,7470 is 2
Step 1: Since 7470 > 794, we apply the division lemma to 7470 and 794, to get
7470 = 794 x 9 + 324
Step 2: Since the reminder 794 ≠ 0, we apply division lemma to 324 and 794, to get
794 = 324 x 2 + 146
Step 3: We consider the new divisor 324 and the new remainder 146, and apply the division lemma to get
324 = 146 x 2 + 32
We consider the new divisor 146 and the new remainder 32,and apply the division lemma to get
146 = 32 x 4 + 18
We consider the new divisor 32 and the new remainder 18,and apply the division lemma to get
32 = 18 x 1 + 14
We consider the new divisor 18 and the new remainder 14,and apply the division lemma to get
18 = 14 x 1 + 4
We consider the new divisor 14 and the new remainder 4,and apply the division lemma to get
14 = 4 x 3 + 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 794 and 7470 is 2
Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(18,14) = HCF(32,18) = HCF(146,32) = HCF(324,146) = HCF(794,324) = HCF(7470,794) .
