HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 754, 591, 512, 85 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 754, 591, 512, 85 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 754, 591, 512, 85 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 754, 591, 512, 85 is 1.
HCF(754, 591, 512, 85) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 754, 591, 512, 85 is 1.
Step 1: Since 754 > 591, we apply the division lemma to 754 and 591, to get
754 = 591 x 1 + 163
Step 2: Since the reminder 591 ≠ 0, we apply division lemma to 163 and 591, to get
591 = 163 x 3 + 102
Step 3: We consider the new divisor 163 and the new remainder 102, and apply the division lemma to get
163 = 102 x 1 + 61
We consider the new divisor 102 and the new remainder 61,and apply the division lemma to get
102 = 61 x 1 + 41
We consider the new divisor 61 and the new remainder 41,and apply the division lemma to get
61 = 41 x 1 + 20
We consider the new divisor 41 and the new remainder 20,and apply the division lemma to get
41 = 20 x 2 + 1
We consider the new divisor 20 and the new remainder 1,and apply the division lemma to get
20 = 1 x 20 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 754 and 591 is 1
Notice that 1 = HCF(20,1) = HCF(41,20) = HCF(61,41) = HCF(102,61) = HCF(163,102) = HCF(591,163) = HCF(754,591) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 512 > 1, we apply the division lemma to 512 and 1, to get
512 = 1 x 512 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 512 is 1
Notice that 1 = HCF(512,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 85 > 1, we apply the division lemma to 85 and 1, to get
85 = 1 x 85 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 85 is 1
Notice that 1 = HCF(85,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
