HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 628, 583, 816 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 628, 583, 816 is 1 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 628, 583, 816 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 628, 583, 816 is 1.
HCF(628, 583, 816) = 1
HCF of 628, 583, 816 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 628, 583, 816 is 1.
Highest Common Factor of 628,583,816 is 1
Step 1: Since 628 > 583, we apply the division lemma to 628 and 583, to get
628 = 583 x 1 + 45
Step 2: Since the reminder 583 ≠ 0, we apply division lemma to 45 and 583, to get
583 = 45 x 12 + 43
Step 3: We consider the new divisor 45 and the new remainder 43, and apply the division lemma to get
45 = 43 x 1 + 2
We consider the new divisor 43 and the new remainder 2,and apply the division lemma to get
43 = 2 x 21 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 628 and 583 is 1
Notice that 1 = HCF(2,1) = HCF(43,2) = HCF(45,43) = HCF(583,45) = HCF(628,583) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 816 > 1, we apply the division lemma to 816 and 1, to get
816 = 1 x 816 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 816 is 1
Notice that 1 = HCF(816,1) .
