HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 551, 997, 442, 544 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 551, 997, 442, 544 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 551, 997, 442, 544 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 551, 997, 442, 544 is 1.
HCF(551, 997, 442, 544) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 551, 997, 442, 544 is 1.
Step 1: Since 997 > 551, we apply the division lemma to 997 and 551, to get
997 = 551 x 1 + 446
Step 2: Since the reminder 551 ≠ 0, we apply division lemma to 446 and 551, to get
551 = 446 x 1 + 105
Step 3: We consider the new divisor 446 and the new remainder 105, and apply the division lemma to get
446 = 105 x 4 + 26
We consider the new divisor 105 and the new remainder 26,and apply the division lemma to get
105 = 26 x 4 + 1
We consider the new divisor 26 and the new remainder 1,and apply the division lemma to get
26 = 1 x 26 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 551 and 997 is 1
Notice that 1 = HCF(26,1) = HCF(105,26) = HCF(446,105) = HCF(551,446) = HCF(997,551) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 442 > 1, we apply the division lemma to 442 and 1, to get
442 = 1 x 442 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 442 is 1
Notice that 1 = HCF(442,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 544 > 1, we apply the division lemma to 544 and 1, to get
544 = 1 x 544 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 544 is 1
Notice that 1 = HCF(544,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
