HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 493, 637, 891, 124 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 493, 637, 891, 124 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, 637, 891, 124 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, 637, 891, 124 is 1.
HCF(493, 637, 891, 124) = 1
HCF of 493, 637, 891, 124 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, 637, 891, 124 is 1.
Highest Common Factor of 493,637,891,124 is 1
Step 1: Since 637 > 493, we apply the division lemma to 637 and 493, to get
637 = 493 x 1 + 144
Step 2: Since the reminder 493 ≠ 0, we apply division lemma to 144 and 493, to get
493 = 144 x 3 + 61
Step 3: We consider the new divisor 144 and the new remainder 61, and apply the division lemma to get
144 = 61 x 2 + 22
We consider the new divisor 61 and the new remainder 22,and apply the division lemma to get
61 = 22 x 2 + 17
We consider the new divisor 22 and the new remainder 17,and apply the division lemma to get
22 = 17 x 1 + 5
We consider the new divisor 17 and the new remainder 5,and apply the division lemma to get
17 = 5 x 3 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 493 and 637 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(17,5) = HCF(22,17) = HCF(61,22) = HCF(144,61) = HCF(493,144) = HCF(637,493) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 891 > 1, we apply the division lemma to 891 and 1, to get
891 = 1 x 891 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 891 is 1
Notice that 1 = HCF(891,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 124 > 1, we apply the division lemma to 124 and 1, to get
124 = 1 x 124 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 124 is 1
Notice that 1 = HCF(124,1) .
