HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 807, 366, 81 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 807, 366, 81 is 3 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 807, 366, 81 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 807, 366, 81 is 3.
HCF(807, 366, 81) = 3
HCF of 807, 366, 81 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 807, 366, 81 is 3.
Highest Common Factor of 807,366,81 is 3
Step 1: Since 807 > 366, we apply the division lemma to 807 and 366, to get
807 = 366 x 2 + 75
Step 2: Since the reminder 366 ≠ 0, we apply division lemma to 75 and 366, to get
366 = 75 x 4 + 66
Step 3: We consider the new divisor 75 and the new remainder 66, and apply the division lemma to get
75 = 66 x 1 + 9
We consider the new divisor 66 and the new remainder 9,and apply the division lemma to get
66 = 9 x 7 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 807 and 366 is 3
Notice that 3 = HCF(9,3) = HCF(66,9) = HCF(75,66) = HCF(366,75) = HCF(807,366) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 81 > 3, we apply the division lemma to 81 and 3, to get
81 = 3 x 27 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 81 is 3
Notice that 3 = HCF(81,3) .
