HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 791, 690, 514, 91 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 791, 690, 514, 91 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 791, 690, 514, 91 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 791, 690, 514, 91 is 1.
HCF(791, 690, 514, 91) = 1
HCF of 791, 690, 514, 91 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 791, 690, 514, 91 is 1.
Highest Common Factor of 791,690,514,91 is 1
Step 1: Since 791 > 690, we apply the division lemma to 791 and 690, to get
791 = 690 x 1 + 101
Step 2: Since the reminder 690 ≠ 0, we apply division lemma to 101 and 690, to get
690 = 101 x 6 + 84
Step 3: We consider the new divisor 101 and the new remainder 84, and apply the division lemma to get
101 = 84 x 1 + 17
We consider the new divisor 84 and the new remainder 17,and apply the division lemma to get
84 = 17 x 4 + 16
We consider the new divisor 17 and the new remainder 16,and apply the division lemma to get
17 = 16 x 1 + 1
We consider the new divisor 16 and the new remainder 1,and apply the division lemma to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 791 and 690 is 1
Notice that 1 = HCF(16,1) = HCF(17,16) = HCF(84,17) = HCF(101,84) = HCF(690,101) = HCF(791,690) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 514 > 1, we apply the division lemma to 514 and 1, to get
514 = 1 x 514 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 514 is 1
Notice that 1 = HCF(514,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 91 > 1, we apply the division lemma to 91 and 1, to get
91 = 1 x 91 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 91 is 1
Notice that 1 = HCF(91,1) .
