HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 551, 413, 378 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 551, 413, 378 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, 413, 378 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, 413, 378 is 1.
HCF(551, 413, 378) = 1
HCF of 551, 413, 378 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 551, 413, 378 is 1.
Highest Common Factor of 551,413,378 is 1
Step 1: Since 551 > 413, we apply the division lemma to 551 and 413, to get
551 = 413 x 1 + 138
Step 2: Since the reminder 413 ≠ 0, we apply division lemma to 138 and 413, to get
413 = 138 x 2 + 137
Step 3: We consider the new divisor 138 and the new remainder 137, and apply the division lemma to get
138 = 137 x 1 + 1
We consider the new divisor 137 and the new remainder 1, and apply the division lemma to get
137 = 1 x 137 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 551 and 413 is 1
Notice that 1 = HCF(137,1) = HCF(138,137) = HCF(413,138) = HCF(551,413) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 378 > 1, we apply the division lemma to 378 and 1, to get
378 = 1 x 378 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 378 is 1
Notice that 1 = HCF(378,1) .
