HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 126, 836 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 126, 836 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 126, 836 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 126, 836 is 2.
HCF(126, 836) = 2
HCF of 126, 836 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 126, 836 is 2.
Highest Common Factor of 126,836 is 2
Step 1: Since 836 > 126, we apply the division lemma to 836 and 126, to get
836 = 126 x 6 + 80
Step 2: Since the reminder 126 ≠ 0, we apply division lemma to 80 and 126, to get
126 = 80 x 1 + 46
Step 3: We consider the new divisor 80 and the new remainder 46, and apply the division lemma to get
80 = 46 x 1 + 34
We consider the new divisor 46 and the new remainder 34,and apply the division lemma to get
46 = 34 x 1 + 12
We consider the new divisor 34 and the new remainder 12,and apply the division lemma to get
34 = 12 x 2 + 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 126 and 836 is 2
Notice that 2 = HCF(10,2) = HCF(12,10) = HCF(34,12) = HCF(46,34) = HCF(80,46) = HCF(126,80) = HCF(836,126) .
