HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 54, 521, 388 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 54, 521, 388 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 54, 521, 388 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 54, 521, 388 is 1.
HCF(54, 521, 388) = 1
HCF of 54, 521, 388 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 54, 521, 388 is 1.
Highest Common Factor of 54,521,388 is 1
Step 1: Since 521 > 54, we apply the division lemma to 521 and 54, to get
521 = 54 x 9 + 35
Step 2: Since the reminder 54 ≠ 0, we apply division lemma to 35 and 54, to get
54 = 35 x 1 + 19
Step 3: We consider the new divisor 35 and the new remainder 19, and apply the division lemma to get
35 = 19 x 1 + 16
We consider the new divisor 19 and the new remainder 16,and apply the division lemma to get
19 = 16 x 1 + 3
We consider the new divisor 16 and the new remainder 3,and apply the division lemma to get
16 = 3 x 5 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 54 and 521 is 1
Notice that 1 = HCF(3,1) = HCF(16,3) = HCF(19,16) = HCF(35,19) = HCF(54,35) = HCF(521,54) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 388 > 1, we apply the division lemma to 388 and 1, to get
388 = 1 x 388 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 388 is 1
Notice that 1 = HCF(388,1) .
