HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 757, 686 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 757, 686 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 757, 686 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 757, 686 is 1.
HCF(757, 686) = 1
HCF of 757, 686 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 757, 686 is 1.
Highest Common Factor of 757,686 is 1
Step 1: Since 757 > 686, we apply the division lemma to 757 and 686, to get
757 = 686 x 1 + 71
Step 2: Since the reminder 686 ≠ 0, we apply division lemma to 71 and 686, to get
686 = 71 x 9 + 47
Step 3: We consider the new divisor 71 and the new remainder 47, and apply the division lemma to get
71 = 47 x 1 + 24
We consider the new divisor 47 and the new remainder 24,and apply the division lemma to get
47 = 24 x 1 + 23
We consider the new divisor 24 and the new remainder 23,and apply the division lemma to get
24 = 23 x 1 + 1
We consider the new divisor 23 and the new remainder 1,and apply the division lemma to get
23 = 1 x 23 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 757 and 686 is 1
Notice that 1 = HCF(23,1) = HCF(24,23) = HCF(47,24) = HCF(71,47) = HCF(686,71) = HCF(757,686) .
