HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 816, 128 i.e. 16 the largest integer that leaves a remainder zero for all numbers.
HCF of 816, 128 is 16 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 816, 128 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 816, 128 is 16.
HCF(816, 128) = 16
HCF of 816, 128 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 816, 128 is 16.
Highest Common Factor of 816,128 is 16
Step 1: Since 816 > 128, we apply the division lemma to 816 and 128, to get
816 = 128 x 6 + 48
Step 2: Since the reminder 128 ≠ 0, we apply division lemma to 48 and 128, to get
128 = 48 x 2 + 32
Step 3: We consider the new divisor 48 and the new remainder 32, and apply the division lemma to get
48 = 32 x 1 + 16
We consider the new divisor 32 and the new remainder 16, and apply the division lemma to get
32 = 16 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 16, the HCF of 816 and 128 is 16
Notice that 16 = HCF(32,16) = HCF(48,32) = HCF(128,48) = HCF(816,128) .
