HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 384, 865, 381 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 384, 865, 381 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 384, 865, 381 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 384, 865, 381 is 1.
HCF(384, 865, 381) = 1
HCF of 384, 865, 381 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 384, 865, 381 is 1.
Highest Common Factor of 384,865,381 is 1
Step 1: Since 865 > 384, we apply the division lemma to 865 and 384, to get
865 = 384 x 2 + 97
Step 2: Since the reminder 384 ≠ 0, we apply division lemma to 97 and 384, to get
384 = 97 x 3 + 93
Step 3: We consider the new divisor 97 and the new remainder 93, and apply the division lemma to get
97 = 93 x 1 + 4
We consider the new divisor 93 and the new remainder 4,and apply the division lemma to get
93 = 4 x 23 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 384 and 865 is 1
Notice that 1 = HCF(4,1) = HCF(93,4) = HCF(97,93) = HCF(384,97) = HCF(865,384) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 381 > 1, we apply the division lemma to 381 and 1, to get
381 = 1 x 381 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 381 is 1
Notice that 1 = HCF(381,1) .
