HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 630, 503, 289, 54 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 630, 503, 289, 54 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 630, 503, 289, 54 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 630, 503, 289, 54 is 1.
HCF(630, 503, 289, 54) = 1
HCF of 630, 503, 289, 54 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 630, 503, 289, 54 is 1.
Highest Common Factor of 630,503,289,54 is 1
Step 1: Since 630 > 503, we apply the division lemma to 630 and 503, to get
630 = 503 x 1 + 127
Step 2: Since the reminder 503 ≠ 0, we apply division lemma to 127 and 503, to get
503 = 127 x 3 + 122
Step 3: We consider the new divisor 127 and the new remainder 122, and apply the division lemma to get
127 = 122 x 1 + 5
We consider the new divisor 122 and the new remainder 5,and apply the division lemma to get
122 = 5 x 24 + 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 630 and 503 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(122,5) = HCF(127,122) = HCF(503,127) = HCF(630,503) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 289 > 1, we apply the division lemma to 289 and 1, to get
289 = 1 x 289 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 289 is 1
Notice that 1 = HCF(289,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 54 > 1, we apply the division lemma to 54 and 1, to get
54 = 1 x 54 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 54 is 1
Notice that 1 = HCF(54,1) .
