HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 800, 816, 786 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 800, 816, 786 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 800, 816, 786 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 800, 816, 786 is 2.
HCF(800, 816, 786) = 2
HCF of 800, 816, 786 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 800, 816, 786 is 2.
Highest Common Factor of 800,816,786 is 2
Step 1: Since 816 > 800, we apply the division lemma to 816 and 800, to get
816 = 800 x 1 + 16
Step 2: Since the reminder 800 ≠ 0, we apply division lemma to 16 and 800, to get
800 = 16 x 50 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 16, the HCF of 800 and 816 is 16
Notice that 16 = HCF(800,16) = HCF(816,800) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 786 > 16, we apply the division lemma to 786 and 16, to get
786 = 16 x 49 + 2
Step 2: Since the reminder 16 ≠ 0, we apply division lemma to 2 and 16, to get
16 = 2 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 16 and 786 is 2
Notice that 2 = HCF(16,2) = HCF(786,16) .
