HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 242, 693, 210, 884 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 242, 693, 210, 884 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 242, 693, 210, 884 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 242, 693, 210, 884 is 1.
HCF(242, 693, 210, 884) = 1
HCF of 242, 693, 210, 884 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 242, 693, 210, 884 is 1.
Highest Common Factor of 242,693,210,884 is 1
Step 1: Since 693 > 242, we apply the division lemma to 693 and 242, to get
693 = 242 x 2 + 209
Step 2: Since the reminder 242 ≠ 0, we apply division lemma to 209 and 242, to get
242 = 209 x 1 + 33
Step 3: We consider the new divisor 209 and the new remainder 33, and apply the division lemma to get
209 = 33 x 6 + 11
We consider the new divisor 33 and the new remainder 11, and apply the division lemma to get
33 = 11 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 242 and 693 is 11
Notice that 11 = HCF(33,11) = HCF(209,33) = HCF(242,209) = HCF(693,242) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 210 > 11, we apply the division lemma to 210 and 11, to get
210 = 11 x 19 + 1
Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 1 and 11, to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 11 and 210 is 1
Notice that 1 = HCF(11,1) = HCF(210,11) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 884 > 1, we apply the division lemma to 884 and 1, to get
884 = 1 x 884 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 884 is 1
Notice that 1 = HCF(884,1) .
