HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 746, 689, 691, 307 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 746, 689, 691, 307 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 746, 689, 691, 307 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 746, 689, 691, 307 is 1.
HCF(746, 689, 691, 307) = 1
HCF of 746, 689, 691, 307 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 746, 689, 691, 307 is 1.
Highest Common Factor of 746,689,691,307 is 1
Step 1: Since 746 > 689, we apply the division lemma to 746 and 689, to get
746 = 689 x 1 + 57
Step 2: Since the reminder 689 ≠ 0, we apply division lemma to 57 and 689, to get
689 = 57 x 12 + 5
Step 3: We consider the new divisor 57 and the new remainder 5, and apply the division lemma to get
57 = 5 x 11 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 746 and 689 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(57,5) = HCF(689,57) = HCF(746,689) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 691 > 1, we apply the division lemma to 691 and 1, to get
691 = 1 x 691 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 691 is 1
Notice that 1 = HCF(691,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 307 > 1, we apply the division lemma to 307 and 1, to get
307 = 1 x 307 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 307 is 1
Notice that 1 = HCF(307,1) .
