HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 634, 878, 124 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 634, 878, 124 is 2 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 634, 878, 124 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 634, 878, 124 is 2.
HCF(634, 878, 124) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 634, 878, 124 is 2.
Step 1: Since 878 > 634, we apply the division lemma to 878 and 634, to get
878 = 634 x 1 + 244
Step 2: Since the reminder 634 ≠ 0, we apply division lemma to 244 and 634, to get
634 = 244 x 2 + 146
Step 3: We consider the new divisor 244 and the new remainder 146, and apply the division lemma to get
244 = 146 x 1 + 98
We consider the new divisor 146 and the new remainder 98,and apply the division lemma to get
146 = 98 x 1 + 48
We consider the new divisor 98 and the new remainder 48,and apply the division lemma to get
98 = 48 x 2 + 2
We consider the new divisor 48 and the new remainder 2,and apply the division lemma to get
48 = 2 x 24 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 634 and 878 is 2
Notice that 2 = HCF(48,2) = HCF(98,48) = HCF(146,98) = HCF(244,146) = HCF(634,244) = HCF(878,634) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 124 > 2, we apply the division lemma to 124 and 2, to get
124 = 2 x 62 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 124 is 2
Notice that 2 = HCF(124,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
