HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 693, 918, 217, 657 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 693, 918, 217, 657 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, 918, 217, 657 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, 918, 217, 657 is 1.
HCF(693, 918, 217, 657) = 1
HCF of 693, 918, 217, 657 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, 918, 217, 657 is 1.
Highest Common Factor of 693,918,217,657 is 1
Step 1: Since 918 > 693, we apply the division lemma to 918 and 693, to get
918 = 693 x 1 + 225
Step 2: Since the reminder 693 ≠ 0, we apply division lemma to 225 and 693, to get
693 = 225 x 3 + 18
Step 3: We consider the new divisor 225 and the new remainder 18, and apply the division lemma to get
225 = 18 x 12 + 9
We consider the new divisor 18 and the new remainder 9, and apply the division lemma to get
18 = 9 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 693 and 918 is 9
Notice that 9 = HCF(18,9) = HCF(225,18) = HCF(693,225) = HCF(918,693) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 217 > 9, we apply the division lemma to 217 and 9, to get
217 = 9 x 24 + 1
Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 1 and 9, to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 9 and 217 is 1
Notice that 1 = HCF(9,1) = HCF(217,9) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 657 > 1, we apply the division lemma to 657 and 1, to get
657 = 1 x 657 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 657 is 1
Notice that 1 = HCF(657,1) .
