HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 769, 637 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 769, 637 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 769, 637 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 769, 637 is 1.
HCF(769, 637) = 1
HCF of 769, 637 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 769, 637 is 1.
Highest Common Factor of 769,637 is 1
Step 1: Since 769 > 637, we apply the division lemma to 769 and 637, to get
769 = 637 x 1 + 132
Step 2: Since the reminder 637 ≠ 0, we apply division lemma to 132 and 637, to get
637 = 132 x 4 + 109
Step 3: We consider the new divisor 132 and the new remainder 109, and apply the division lemma to get
132 = 109 x 1 + 23
We consider the new divisor 109 and the new remainder 23,and apply the division lemma to get
109 = 23 x 4 + 17
We consider the new divisor 23 and the new remainder 17,and apply the division lemma to get
23 = 17 x 1 + 6
We consider the new divisor 17 and the new remainder 6,and apply the division lemma to get
17 = 6 x 2 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 769 and 637 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(17,6) = HCF(23,17) = HCF(109,23) = HCF(132,109) = HCF(637,132) = HCF(769,637) .
