HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 528, 728, 878 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 528, 728, 878 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 528, 728, 878 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 528, 728, 878 is 2.
HCF(528, 728, 878) = 2
HCF of 528, 728, 878 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 528, 728, 878 is 2.
Highest Common Factor of 528,728,878 is 2
Step 1: Since 728 > 528, we apply the division lemma to 728 and 528, to get
728 = 528 x 1 + 200
Step 2: Since the reminder 528 ≠ 0, we apply division lemma to 200 and 528, to get
528 = 200 x 2 + 128
Step 3: We consider the new divisor 200 and the new remainder 128, and apply the division lemma to get
200 = 128 x 1 + 72
We consider the new divisor 128 and the new remainder 72,and apply the division lemma to get
128 = 72 x 1 + 56
We consider the new divisor 72 and the new remainder 56,and apply the division lemma to get
72 = 56 x 1 + 16
We consider the new divisor 56 and the new remainder 16,and apply the division lemma to get
56 = 16 x 3 + 8
We consider the new divisor 16 and the new remainder 8,and apply the division lemma to get
16 = 8 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 528 and 728 is 8
Notice that 8 = HCF(16,8) = HCF(56,16) = HCF(72,56) = HCF(128,72) = HCF(200,128) = HCF(528,200) = HCF(728,528) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 878 > 8, we apply the division lemma to 878 and 8, to get
878 = 8 x 109 + 6
Step 2: Since the reminder 8 ≠ 0, we apply division lemma to 6 and 8, to get
8 = 6 x 1 + 2
Step 3: 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 8 and 878 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(878,8) .
