HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 683, 383, 457 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 683, 383, 457 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 683, 383, 457 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 683, 383, 457 is 1.
HCF(683, 383, 457) = 1
HCF of 683, 383, 457 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 683, 383, 457 is 1.
Highest Common Factor of 683,383,457 is 1
Step 1: Since 683 > 383, we apply the division lemma to 683 and 383, to get
683 = 383 x 1 + 300
Step 2: Since the reminder 383 ≠ 0, we apply division lemma to 300 and 383, to get
383 = 300 x 1 + 83
Step 3: We consider the new divisor 300 and the new remainder 83, and apply the division lemma to get
300 = 83 x 3 + 51
We consider the new divisor 83 and the new remainder 51,and apply the division lemma to get
83 = 51 x 1 + 32
We consider the new divisor 51 and the new remainder 32,and apply the division lemma to get
51 = 32 x 1 + 19
We consider the new divisor 32 and the new remainder 19,and apply the division lemma to get
32 = 19 x 1 + 13
We consider the new divisor 19 and the new remainder 13,and apply the division lemma to get
19 = 13 x 1 + 6
We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get
13 = 6 x 2 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 683 and 383 is 1
Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(19,13) = HCF(32,19) = HCF(51,32) = HCF(83,51) = HCF(300,83) = HCF(383,300) = HCF(683,383) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 457 > 1, we apply the division lemma to 457 and 1, to get
457 = 1 x 457 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 457 is 1
Notice that 1 = HCF(457,1) .
