HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 65, 817, 992 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 65, 817, 992 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 65, 817, 992 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 65, 817, 992 is 1.
HCF(65, 817, 992) = 1
HCF of 65, 817, 992 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 65, 817, 992 is 1.
Highest Common Factor of 65,817,992 is 1
Step 1: Since 817 > 65, we apply the division lemma to 817 and 65, to get
817 = 65 x 12 + 37
Step 2: Since the reminder 65 ≠ 0, we apply division lemma to 37 and 65, to get
65 = 37 x 1 + 28
Step 3: We consider the new divisor 37 and the new remainder 28, and apply the division lemma to get
37 = 28 x 1 + 9
We consider the new divisor 28 and the new remainder 9,and apply the division lemma to get
28 = 9 x 3 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 65 and 817 is 1
Notice that 1 = HCF(9,1) = HCF(28,9) = HCF(37,28) = HCF(65,37) = HCF(817,65) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 992 > 1, we apply the division lemma to 992 and 1, to get
992 = 1 x 992 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 992 is 1
Notice that 1 = HCF(992,1) .
