HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 626, 788, 485 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 626, 788, 485 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 626, 788, 485 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 626, 788, 485 is 1.
HCF(626, 788, 485) = 1
HCF of 626, 788, 485 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 626, 788, 485 is 1.
Highest Common Factor of 626,788,485 is 1
Step 1: Since 788 > 626, we apply the division lemma to 788 and 626, to get
788 = 626 x 1 + 162
Step 2: Since the reminder 626 ≠ 0, we apply division lemma to 162 and 626, to get
626 = 162 x 3 + 140
Step 3: We consider the new divisor 162 and the new remainder 140, and apply the division lemma to get
162 = 140 x 1 + 22
We consider the new divisor 140 and the new remainder 22,and apply the division lemma to get
140 = 22 x 6 + 8
We consider the new divisor 22 and the new remainder 8,and apply the division lemma to get
22 = 8 x 2 + 6
We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get
8 = 6 x 1 + 2
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 626 and 788 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(22,8) = HCF(140,22) = HCF(162,140) = HCF(626,162) = HCF(788,626) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 485 > 2, we apply the division lemma to 485 and 2, to get
485 = 2 x 242 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 485 is 1
Notice that 1 = HCF(2,1) = HCF(485,2) .
