HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 485, 254, 654, 239 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 485, 254, 654, 239 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 485, 254, 654, 239 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 485, 254, 654, 239 is 1.
HCF(485, 254, 654, 239) = 1
HCF of 485, 254, 654, 239 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 485, 254, 654, 239 is 1.
Highest Common Factor of 485,254,654,239 is 1
Step 1: Since 485 > 254, we apply the division lemma to 485 and 254, to get
485 = 254 x 1 + 231
Step 2: Since the reminder 254 ≠ 0, we apply division lemma to 231 and 254, to get
254 = 231 x 1 + 23
Step 3: We consider the new divisor 231 and the new remainder 23, and apply the division lemma to get
231 = 23 x 10 + 1
We consider the new divisor 23 and the new remainder 1, and apply the division lemma to get
23 = 1 x 23 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 485 and 254 is 1
Notice that 1 = HCF(23,1) = HCF(231,23) = HCF(254,231) = HCF(485,254) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 654 > 1, we apply the division lemma to 654 and 1, to get
654 = 1 x 654 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 654 is 1
Notice that 1 = HCF(654,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 239 > 1, we apply the division lemma to 239 and 1, to get
239 = 1 x 239 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 239 is 1
Notice that 1 = HCF(239,1) .
