HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 68, 51, 900 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 68, 51, 900 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 68, 51, 900 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 68, 51, 900 is 1.
HCF(68, 51, 900) = 1
HCF of 68, 51, 900 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 68, 51, 900 is 1.
Highest Common Factor of 68,51,900 is 1
Step 1: Since 68 > 51, we apply the division lemma to 68 and 51, to get
68 = 51 x 1 + 17
Step 2: Since the reminder 51 ≠ 0, we apply division lemma to 17 and 51, to get
51 = 17 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 17, the HCF of 68 and 51 is 17
Notice that 17 = HCF(51,17) = HCF(68,51) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 900 > 17, we apply the division lemma to 900 and 17, to get
900 = 17 x 52 + 16
Step 2: Since the reminder 17 ≠ 0, we apply division lemma to 16 and 17, to get
17 = 16 x 1 + 1
Step 3: We consider the new divisor 16 and the new remainder 1, and apply the division lemma to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 17 and 900 is 1
Notice that 1 = HCF(16,1) = HCF(17,16) = HCF(900,17) .
