HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 18, 15, 832, 693 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 18, 15, 832, 693 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 18, 15, 832, 693 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 18, 15, 832, 693 is 1.
HCF(18, 15, 832, 693) = 1
HCF of 18, 15, 832, 693 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 18, 15, 832, 693 is 1.
Highest Common Factor of 18,15,832,693 is 1
Step 1: Since 18 > 15, we apply the division lemma to 18 and 15, to get
18 = 15 x 1 + 3
Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 3 and 15, to get
15 = 3 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 18 and 15 is 3
Notice that 3 = HCF(15,3) = HCF(18,15) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 832 > 3, we apply the division lemma to 832 and 3, to get
832 = 3 x 277 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 832 is 1
Notice that 1 = HCF(3,1) = HCF(832,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 693 > 1, we apply the division lemma to 693 and 1, to get
693 = 1 x 693 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 693 is 1
Notice that 1 = HCF(693,1) .
