HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 816, 920, 546 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 816, 920, 546 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 816, 920, 546 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, 920, 546 is 2.
HCF(816, 920, 546) = 2
HCF of 816, 920, 546 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, 920, 546 is 2.
Highest Common Factor of 816,920,546 is 2
Step 1: Since 920 > 816, we apply the division lemma to 920 and 816, to get
920 = 816 x 1 + 104
Step 2: Since the reminder 816 ≠ 0, we apply division lemma to 104 and 816, to get
816 = 104 x 7 + 88
Step 3: We consider the new divisor 104 and the new remainder 88, and apply the division lemma to get
104 = 88 x 1 + 16
We consider the new divisor 88 and the new remainder 16,and apply the division lemma to get
88 = 16 x 5 + 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 816 and 920 is 8
Notice that 8 = HCF(16,8) = HCF(88,16) = HCF(104,88) = HCF(816,104) = HCF(920,816) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 546 > 8, we apply the division lemma to 546 and 8, to get
546 = 8 x 68 + 2
Step 2: Since the reminder 8 ≠ 0, we apply division lemma to 2 and 8, to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 8 and 546 is 2
Notice that 2 = HCF(8,2) = HCF(546,8) .
