HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 976, 634, 203 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 976, 634, 203 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 976, 634, 203 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 976, 634, 203 is 1.
HCF(976, 634, 203) = 1
HCF of 976, 634, 203 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 976, 634, 203 is 1.
Highest Common Factor of 976,634,203 is 1
Step 1: Since 976 > 634, we apply the division lemma to 976 and 634, to get
976 = 634 x 1 + 342
Step 2: Since the reminder 634 ≠ 0, we apply division lemma to 342 and 634, to get
634 = 342 x 1 + 292
Step 3: We consider the new divisor 342 and the new remainder 292, and apply the division lemma to get
342 = 292 x 1 + 50
We consider the new divisor 292 and the new remainder 50,and apply the division lemma to get
292 = 50 x 5 + 42
We consider the new divisor 50 and the new remainder 42,and apply the division lemma to get
50 = 42 x 1 + 8
We consider the new divisor 42 and the new remainder 8,and apply the division lemma to get
42 = 8 x 5 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 976 and 634 is 2
Notice that 2 = HCF(8,2) = HCF(42,8) = HCF(50,42) = HCF(292,50) = HCF(342,292) = HCF(634,342) = HCF(976,634) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 203 > 2, we apply the division lemma to 203 and 2, to get
203 = 2 x 101 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 203 is 1
Notice that 1 = HCF(2,1) = HCF(203,2) .
