HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 805, 927, 392 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 805, 927, 392 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 805, 927, 392 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 805, 927, 392 is 1.
HCF(805, 927, 392) = 1
HCF of 805, 927, 392 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 805, 927, 392 is 1.
Highest Common Factor of 805,927,392 is 1
Step 1: Since 927 > 805, we apply the division lemma to 927 and 805, to get
927 = 805 x 1 + 122
Step 2: Since the reminder 805 ≠ 0, we apply division lemma to 122 and 805, to get
805 = 122 x 6 + 73
Step 3: We consider the new divisor 122 and the new remainder 73, and apply the division lemma to get
122 = 73 x 1 + 49
We consider the new divisor 73 and the new remainder 49,and apply the division lemma to get
73 = 49 x 1 + 24
We consider the new divisor 49 and the new remainder 24,and apply the division lemma to get
49 = 24 x 2 + 1
We consider the new divisor 24 and the new remainder 1,and apply the division lemma to get
24 = 1 x 24 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 805 and 927 is 1
Notice that 1 = HCF(24,1) = HCF(49,24) = HCF(73,49) = HCF(122,73) = HCF(805,122) = HCF(927,805) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 392 > 1, we apply the division lemma to 392 and 1, to get
392 = 1 x 392 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 392 is 1
Notice that 1 = HCF(392,1) .
