HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 210, 788, 897 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 210, 788, 897 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 210, 788, 897 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 210, 788, 897 is 1.
HCF(210, 788, 897) = 1
HCF of 210, 788, 897 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 210, 788, 897 is 1.
Highest Common Factor of 210,788,897 is 1
Step 1: Since 788 > 210, we apply the division lemma to 788 and 210, to get
788 = 210 x 3 + 158
Step 2: Since the reminder 210 ≠ 0, we apply division lemma to 158 and 210, to get
210 = 158 x 1 + 52
Step 3: We consider the new divisor 158 and the new remainder 52, and apply the division lemma to get
158 = 52 x 3 + 2
We consider the new divisor 52 and the new remainder 2, and apply the division lemma to get
52 = 2 x 26 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 210 and 788 is 2
Notice that 2 = HCF(52,2) = HCF(158,52) = HCF(210,158) = HCF(788,210) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 897 > 2, we apply the division lemma to 897 and 2, to get
897 = 2 x 448 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 897 is 1
Notice that 1 = HCF(2,1) = HCF(897,2) .
