HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 255, 897, 651 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 255, 897, 651 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 255, 897, 651 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 255, 897, 651 is 3.
HCF(255, 897, 651) = 3
HCF of 255, 897, 651 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 255, 897, 651 is 3.
Highest Common Factor of 255,897,651 is 3
Step 1: Since 897 > 255, we apply the division lemma to 897 and 255, to get
897 = 255 x 3 + 132
Step 2: Since the reminder 255 ≠ 0, we apply division lemma to 132 and 255, to get
255 = 132 x 1 + 123
Step 3: We consider the new divisor 132 and the new remainder 123, and apply the division lemma to get
132 = 123 x 1 + 9
We consider the new divisor 123 and the new remainder 9,and apply the division lemma to get
123 = 9 x 13 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 255 and 897 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(123,9) = HCF(132,123) = HCF(255,132) = HCF(897,255) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 651 > 3, we apply the division lemma to 651 and 3, to get
651 = 3 x 217 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 651 is 3
Notice that 3 = HCF(651,3) .
