HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 997, 527, 634, 384 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 997, 527, 634, 384 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, 527, 634, 384 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, 527, 634, 384 is 1.
HCF(997, 527, 634, 384) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 997, 527, 634, 384 is 1.
Step 1: Since 997 > 527, we apply the division lemma to 997 and 527, to get
997 = 527 x 1 + 470
Step 2: Since the reminder 527 ≠ 0, we apply division lemma to 470 and 527, to get
527 = 470 x 1 + 57
Step 3: We consider the new divisor 470 and the new remainder 57, and apply the division lemma to get
470 = 57 x 8 + 14
We consider the new divisor 57 and the new remainder 14,and apply the division lemma to get
57 = 14 x 4 + 1
We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get
14 = 1 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 997 and 527 is 1
Notice that 1 = HCF(14,1) = HCF(57,14) = HCF(470,57) = HCF(527,470) = HCF(997,527) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 634 > 1, we apply the division lemma to 634 and 1, to get
634 = 1 x 634 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 634 is 1
Notice that 1 = HCF(634,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 384 > 1, we apply the division lemma to 384 and 1, to get
384 = 1 x 384 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 384 is 1
Notice that 1 = HCF(384,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
