HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 624, 338, 961, 257 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 624, 338, 961, 257 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 624, 338, 961, 257 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 624, 338, 961, 257 is 1.
HCF(624, 338, 961, 257) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 624, 338, 961, 257 is 1.
Step 1: Since 624 > 338, we apply the division lemma to 624 and 338, to get
624 = 338 x 1 + 286
Step 2: Since the reminder 338 ≠ 0, we apply division lemma to 286 and 338, to get
338 = 286 x 1 + 52
Step 3: We consider the new divisor 286 and the new remainder 52, and apply the division lemma to get
286 = 52 x 5 + 26
We consider the new divisor 52 and the new remainder 26, and apply the division lemma to get
52 = 26 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 26, the HCF of 624 and 338 is 26
Notice that 26 = HCF(52,26) = HCF(286,52) = HCF(338,286) = HCF(624,338) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 961 > 26, we apply the division lemma to 961 and 26, to get
961 = 26 x 36 + 25
Step 2: Since the reminder 26 ≠ 0, we apply division lemma to 25 and 26, to get
26 = 25 x 1 + 1
Step 3: We consider the new divisor 25 and the new remainder 1, and apply the division lemma to get
25 = 1 x 25 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 26 and 961 is 1
Notice that 1 = HCF(25,1) = HCF(26,25) = HCF(961,26) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 257 > 1, we apply the division lemma to 257 and 1, to get
257 = 1 x 257 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 257 is 1
Notice that 1 = HCF(257,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
