HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 634, 37689 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 634, 37689 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 634, 37689 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 634, 37689 is 1.
HCF(634, 37689) = 1
HCF of 634, 37689 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 634, 37689 is 1.
Highest Common Factor of 634,37689 is 1
Step 1: Since 37689 > 634, we apply the division lemma to 37689 and 634, to get
37689 = 634 x 59 + 283
Step 2: Since the reminder 634 ≠ 0, we apply division lemma to 283 and 634, to get
634 = 283 x 2 + 68
Step 3: We consider the new divisor 283 and the new remainder 68, and apply the division lemma to get
283 = 68 x 4 + 11
We consider the new divisor 68 and the new remainder 11,and apply the division lemma to get
68 = 11 x 6 + 2
We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get
11 = 2 x 5 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 634 and 37689 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(68,11) = HCF(283,68) = HCF(634,283) = HCF(37689,634) .
