HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 630, 878, 724 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 630, 878, 724 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 630, 878, 724 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 630, 878, 724 is 2.
HCF(630, 878, 724) = 2
HCF of 630, 878, 724 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 630, 878, 724 is 2.
Highest Common Factor of 630,878,724 is 2
Step 1: Since 878 > 630, we apply the division lemma to 878 and 630, to get
878 = 630 x 1 + 248
Step 2: Since the reminder 630 ≠ 0, we apply division lemma to 248 and 630, to get
630 = 248 x 2 + 134
Step 3: We consider the new divisor 248 and the new remainder 134, and apply the division lemma to get
248 = 134 x 1 + 114
We consider the new divisor 134 and the new remainder 114,and apply the division lemma to get
134 = 114 x 1 + 20
We consider the new divisor 114 and the new remainder 20,and apply the division lemma to get
114 = 20 x 5 + 14
We consider the new divisor 20 and the new remainder 14,and apply the division lemma to get
20 = 14 x 1 + 6
We consider the new divisor 14 and the new remainder 6,and apply the division lemma to get
14 = 6 x 2 + 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 630 and 878 is 2
Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(20,14) = HCF(114,20) = HCF(134,114) = HCF(248,134) = HCF(630,248) = HCF(878,630) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 724 > 2, we apply the division lemma to 724 and 2, to get
724 = 2 x 362 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 724 is 2
Notice that 2 = HCF(724,2) .
