HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 298, 788, 50 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 298, 788, 50 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 298, 788, 50 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 298, 788, 50 is 2.
HCF(298, 788, 50) = 2
HCF of 298, 788, 50 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 298, 788, 50 is 2.
Highest Common Factor of 298,788,50 is 2
Step 1: Since 788 > 298, we apply the division lemma to 788 and 298, to get
788 = 298 x 2 + 192
Step 2: Since the reminder 298 ≠ 0, we apply division lemma to 192 and 298, to get
298 = 192 x 1 + 106
Step 3: We consider the new divisor 192 and the new remainder 106, and apply the division lemma to get
192 = 106 x 1 + 86
We consider the new divisor 106 and the new remainder 86,and apply the division lemma to get
106 = 86 x 1 + 20
We consider the new divisor 86 and the new remainder 20,and apply the division lemma to get
86 = 20 x 4 + 6
We consider the new divisor 20 and the new remainder 6,and apply the division lemma to get
20 = 6 x 3 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 298 and 788 is 2
Notice that 2 = HCF(6,2) = HCF(20,6) = HCF(86,20) = HCF(106,86) = HCF(192,106) = HCF(298,192) = HCF(788,298) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 50 > 2, we apply the division lemma to 50 and 2, to get
50 = 2 x 25 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 50 is 2
Notice that 2 = HCF(50,2) .
