HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 872, 998, 782 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 872, 998, 782 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 872, 998, 782 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 872, 998, 782 is 2.
HCF(872, 998, 782) = 2
HCF of 872, 998, 782 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 872, 998, 782 is 2.
Highest Common Factor of 872,998,782 is 2
Step 1: Since 998 > 872, we apply the division lemma to 998 and 872, to get
998 = 872 x 1 + 126
Step 2: Since the reminder 872 ≠ 0, we apply division lemma to 126 and 872, to get
872 = 126 x 6 + 116
Step 3: We consider the new divisor 126 and the new remainder 116, and apply the division lemma to get
126 = 116 x 1 + 10
We consider the new divisor 116 and the new remainder 10,and apply the division lemma to get
116 = 10 x 11 + 6
We consider the new divisor 10 and the new remainder 6,and apply the division lemma to get
10 = 6 x 1 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 872 and 998 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(116,10) = HCF(126,116) = HCF(872,126) = HCF(998,872) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 782 > 2, we apply the division lemma to 782 and 2, to get
782 = 2 x 391 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 782 is 2
Notice that 2 = HCF(782,2) .
