HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 493, 801, 626 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 493, 801, 626 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 493, 801, 626 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 493, 801, 626 is 1.
HCF(493, 801, 626) = 1
HCF of 493, 801, 626 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 493, 801, 626 is 1.
Highest Common Factor of 493,801,626 is 1
Step 1: Since 801 > 493, we apply the division lemma to 801 and 493, to get
801 = 493 x 1 + 308
Step 2: Since the reminder 493 ≠ 0, we apply division lemma to 308 and 493, to get
493 = 308 x 1 + 185
Step 3: We consider the new divisor 308 and the new remainder 185, and apply the division lemma to get
308 = 185 x 1 + 123
We consider the new divisor 185 and the new remainder 123,and apply the division lemma to get
185 = 123 x 1 + 62
We consider the new divisor 123 and the new remainder 62,and apply the division lemma to get
123 = 62 x 1 + 61
We consider the new divisor 62 and the new remainder 61,and apply the division lemma to get
62 = 61 x 1 + 1
We consider the new divisor 61 and the new remainder 1,and apply the division lemma to get
61 = 1 x 61 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 493 and 801 is 1
Notice that 1 = HCF(61,1) = HCF(62,61) = HCF(123,62) = HCF(185,123) = HCF(308,185) = HCF(493,308) = HCF(801,493) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 626 > 1, we apply the division lemma to 626 and 1, to get
626 = 1 x 626 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 626 is 1
Notice that 1 = HCF(626,1) .
