HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 997, 333, 152, 51 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 997, 333, 152, 51 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 997, 333, 152, 51 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 997, 333, 152, 51 is 1.
HCF(997, 333, 152, 51) = 1
HCF of 997, 333, 152, 51 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 997, 333, 152, 51 is 1.
Highest Common Factor of 997,333,152,51 is 1
Step 1: Since 997 > 333, we apply the division lemma to 997 and 333, to get
997 = 333 x 2 + 331
Step 2: Since the reminder 333 ≠ 0, we apply division lemma to 331 and 333, to get
333 = 331 x 1 + 2
Step 3: We consider the new divisor 331 and the new remainder 2, and apply the division lemma to get
331 = 2 x 165 + 1
We consider the new divisor 2 and the new remainder 1, and apply the division lemma 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 997 and 333 is 1
Notice that 1 = HCF(2,1) = HCF(331,2) = HCF(333,331) = HCF(997,333) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 152 > 1, we apply the division lemma to 152 and 1, to get
152 = 1 x 152 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 152 is 1
Notice that 1 = HCF(152,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 51 > 1, we apply the division lemma to 51 and 1, to get
51 = 1 x 51 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 51 is 1
Notice that 1 = HCF(51,1) .
