HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 728, 7748, 7860 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 728, 7748, 7860 is 4 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 728, 7748, 7860 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 728, 7748, 7860 is 4.
HCF(728, 7748, 7860) = 4
HCF of 728, 7748, 7860 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 728, 7748, 7860 is 4.
Highest Common Factor of 728,7748,7860 is 4
Step 1: Since 7748 > 728, we apply the division lemma to 7748 and 728, to get
7748 = 728 x 10 + 468
Step 2: Since the reminder 728 ≠ 0, we apply division lemma to 468 and 728, to get
728 = 468 x 1 + 260
Step 3: We consider the new divisor 468 and the new remainder 260, and apply the division lemma to get
468 = 260 x 1 + 208
We consider the new divisor 260 and the new remainder 208,and apply the division lemma to get
260 = 208 x 1 + 52
We consider the new divisor 208 and the new remainder 52,and apply the division lemma to get
208 = 52 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 52, the HCF of 728 and 7748 is 52
Notice that 52 = HCF(208,52) = HCF(260,208) = HCF(468,260) = HCF(728,468) = HCF(7748,728) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 7860 > 52, we apply the division lemma to 7860 and 52, to get
7860 = 52 x 151 + 8
Step 2: Since the reminder 52 ≠ 0, we apply division lemma to 8 and 52, to get
52 = 8 x 6 + 4
Step 3: We consider the new divisor 8 and the new remainder 4, and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 52 and 7860 is 4
Notice that 4 = HCF(8,4) = HCF(52,8) = HCF(7860,52) .
