HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 626, 742, 126 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 626, 742, 126 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 626, 742, 126 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 626, 742, 126 is 2.
HCF(626, 742, 126) = 2
HCF of 626, 742, 126 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 626, 742, 126 is 2.
Highest Common Factor of 626,742,126 is 2
Step 1: Since 742 > 626, we apply the division lemma to 742 and 626, to get
742 = 626 x 1 + 116
Step 2: Since the reminder 626 ≠ 0, we apply division lemma to 116 and 626, to get
626 = 116 x 5 + 46
Step 3: We consider the new divisor 116 and the new remainder 46, and apply the division lemma to get
116 = 46 x 2 + 24
We consider the new divisor 46 and the new remainder 24,and apply the division lemma to get
46 = 24 x 1 + 22
We consider the new divisor 24 and the new remainder 22,and apply the division lemma to get
24 = 22 x 1 + 2
We consider the new divisor 22 and the new remainder 2,and apply the division lemma to get
22 = 2 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 626 and 742 is 2
Notice that 2 = HCF(22,2) = HCF(24,22) = HCF(46,24) = HCF(116,46) = HCF(626,116) = HCF(742,626) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 126 > 2, we apply the division lemma to 126 and 2, to get
126 = 2 x 63 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 126 is 2
Notice that 2 = HCF(126,2) .
