HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 392, 802, 383 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 392, 802, 383 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 392, 802, 383 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 392, 802, 383 is 1.
HCF(392, 802, 383) = 1
HCF of 392, 802, 383 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 392, 802, 383 is 1.
Highest Common Factor of 392,802,383 is 1
Step 1: Since 802 > 392, we apply the division lemma to 802 and 392, to get
802 = 392 x 2 + 18
Step 2: Since the reminder 392 ≠ 0, we apply division lemma to 18 and 392, to get
392 = 18 x 21 + 14
Step 3: We consider the new divisor 18 and the new remainder 14, and apply the division lemma to get
18 = 14 x 1 + 4
We consider the new divisor 14 and the new remainder 4,and apply the division lemma to get
14 = 4 x 3 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 392 and 802 is 2
Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(18,14) = HCF(392,18) = HCF(802,392) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 383 > 2, we apply the division lemma to 383 and 2, to get
383 = 2 x 191 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 383 is 1
Notice that 1 = HCF(2,1) = HCF(383,2) .
