HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 827, 645, 866 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 827, 645, 866 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 827, 645, 866 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 827, 645, 866 is 1.
HCF(827, 645, 866) = 1
HCF of 827, 645, 866 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 827, 645, 866 is 1.
Highest Common Factor of 827,645,866 is 1
Step 1: Since 827 > 645, we apply the division lemma to 827 and 645, to get
827 = 645 x 1 + 182
Step 2: Since the reminder 645 ≠ 0, we apply division lemma to 182 and 645, to get
645 = 182 x 3 + 99
Step 3: We consider the new divisor 182 and the new remainder 99, and apply the division lemma to get
182 = 99 x 1 + 83
We consider the new divisor 99 and the new remainder 83,and apply the division lemma to get
99 = 83 x 1 + 16
We consider the new divisor 83 and the new remainder 16,and apply the division lemma to get
83 = 16 x 5 + 3
We consider the new divisor 16 and the new remainder 3,and apply the division lemma to get
16 = 3 x 5 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 827 and 645 is 1
Notice that 1 = HCF(3,1) = HCF(16,3) = HCF(83,16) = HCF(99,83) = HCF(182,99) = HCF(645,182) = HCF(827,645) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 866 > 1, we apply the division lemma to 866 and 1, to get
866 = 1 x 866 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 866 is 1
Notice that 1 = HCF(866,1) .
