HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 693, 313, 923 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 693, 313, 923 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 693, 313, 923 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 693, 313, 923 is 1.
HCF(693, 313, 923) = 1
HCF of 693, 313, 923 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 693, 313, 923 is 1.
Highest Common Factor of 693,313,923 is 1
Step 1: Since 693 > 313, we apply the division lemma to 693 and 313, to get
693 = 313 x 2 + 67
Step 2: Since the reminder 313 ≠ 0, we apply division lemma to 67 and 313, to get
313 = 67 x 4 + 45
Step 3: We consider the new divisor 67 and the new remainder 45, and apply the division lemma to get
67 = 45 x 1 + 22
We consider the new divisor 45 and the new remainder 22,and apply the division lemma to get
45 = 22 x 2 + 1
We consider the new divisor 22 and the new remainder 1,and apply the division lemma to get
22 = 1 x 22 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 693 and 313 is 1
Notice that 1 = HCF(22,1) = HCF(45,22) = HCF(67,45) = HCF(313,67) = HCF(693,313) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 923 > 1, we apply the division lemma to 923 and 1, to get
923 = 1 x 923 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 923 is 1
Notice that 1 = HCF(923,1) .
