HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 840, 794 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 840, 794 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 840, 794 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 840, 794 is 2.
HCF(840, 794) = 2
HCF of 840, 794 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 840, 794 is 2.
Highest Common Factor of 840,794 is 2
Step 1: Since 840 > 794, we apply the division lemma to 840 and 794, to get
840 = 794 x 1 + 46
Step 2: Since the reminder 794 ≠ 0, we apply division lemma to 46 and 794, to get
794 = 46 x 17 + 12
Step 3: We consider the new divisor 46 and the new remainder 12, and apply the division lemma to get
46 = 12 x 3 + 10
We consider the new divisor 12 and the new remainder 10,and apply the division lemma to get
12 = 10 x 1 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 840 and 794 is 2
Notice that 2 = HCF(10,2) = HCF(12,10) = HCF(46,12) = HCF(794,46) = HCF(840,794) .
