HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 81, 851, 468 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 81, 851, 468 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 81, 851, 468 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 81, 851, 468 is 1.
HCF(81, 851, 468) = 1
HCF of 81, 851, 468 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 81, 851, 468 is 1.
Highest Common Factor of 81,851,468 is 1
Step 1: Since 851 > 81, we apply the division lemma to 851 and 81, to get
851 = 81 x 10 + 41
Step 2: Since the reminder 81 ≠ 0, we apply division lemma to 41 and 81, to get
81 = 41 x 1 + 40
Step 3: We consider the new divisor 41 and the new remainder 40, and apply the division lemma to get
41 = 40 x 1 + 1
We consider the new divisor 40 and the new remainder 1, and apply the division lemma to get
40 = 1 x 40 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 81 and 851 is 1
Notice that 1 = HCF(40,1) = HCF(41,40) = HCF(81,41) = HCF(851,81) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 468 > 1, we apply the division lemma to 468 and 1, to get
468 = 1 x 468 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 468 is 1
Notice that 1 = HCF(468,1) .
