HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 178, 838, 380, 551 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 178, 838, 380, 551 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 178, 838, 380, 551 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 178, 838, 380, 551 is 1.
HCF(178, 838, 380, 551) = 1
HCF of 178, 838, 380, 551 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 178, 838, 380, 551 is 1.
Highest Common Factor of 178,838,380,551 is 1
Step 1: Since 838 > 178, we apply the division lemma to 838 and 178, to get
838 = 178 x 4 + 126
Step 2: Since the reminder 178 ≠ 0, we apply division lemma to 126 and 178, to get
178 = 126 x 1 + 52
Step 3: We consider the new divisor 126 and the new remainder 52, and apply the division lemma to get
126 = 52 x 2 + 22
We consider the new divisor 52 and the new remainder 22,and apply the division lemma to get
52 = 22 x 2 + 8
We consider the new divisor 22 and the new remainder 8,and apply the division lemma to get
22 = 8 x 2 + 6
We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get
8 = 6 x 1 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 178 and 838 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(22,8) = HCF(52,22) = HCF(126,52) = HCF(178,126) = HCF(838,178) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 380 > 2, we apply the division lemma to 380 and 2, to get
380 = 2 x 190 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 380 is 2
Notice that 2 = HCF(380,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 551 > 2, we apply the division lemma to 551 and 2, to get
551 = 2 x 275 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 551 is 1
Notice that 1 = HCF(2,1) = HCF(551,2) .
