HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 126, 469, 762 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 126, 469, 762 is 1 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, 469, 762 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, 469, 762 is 1.
HCF(126, 469, 762) = 1
HCF of 126, 469, 762 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, 469, 762 is 1.
Highest Common Factor of 126,469,762 is 1
Step 1: Since 469 > 126, we apply the division lemma to 469 and 126, to get
469 = 126 x 3 + 91
Step 2: Since the reminder 126 ≠ 0, we apply division lemma to 91 and 126, to get
126 = 91 x 1 + 35
Step 3: We consider the new divisor 91 and the new remainder 35, and apply the division lemma to get
91 = 35 x 2 + 21
We consider the new divisor 35 and the new remainder 21,and apply the division lemma to get
35 = 21 x 1 + 14
We consider the new divisor 21 and the new remainder 14,and apply the division lemma to get
21 = 14 x 1 + 7
We consider the new divisor 14 and the new remainder 7,and apply the division lemma to get
14 = 7 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 126 and 469 is 7
Notice that 7 = HCF(14,7) = HCF(21,14) = HCF(35,21) = HCF(91,35) = HCF(126,91) = HCF(469,126) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 762 > 7, we apply the division lemma to 762 and 7, to get
762 = 7 x 108 + 6
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 6 and 7, to get
7 = 6 x 1 + 1
Step 3: We consider the new divisor 6 and the new remainder 1, and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7 and 762 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(762,7) .
