HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 120, 123, 897 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 120, 123, 897 is 3 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 120, 123, 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 120, 123, 897 is 3.
HCF(120, 123, 897) = 3
HCF of 120, 123, 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 120, 123, 897 is 3.
Highest Common Factor of 120,123,897 is 3
Step 1: Since 123 > 120, we apply the division lemma to 123 and 120, to get
123 = 120 x 1 + 3
Step 2: Since the reminder 120 ≠ 0, we apply division lemma to 3 and 120, to get
120 = 3 x 40 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 120 and 123 is 3
Notice that 3 = HCF(120,3) = HCF(123,120) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 897 > 3, we apply the division lemma to 897 and 3, to get
897 = 3 x 299 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 897 is 3
Notice that 3 = HCF(897,3) .
