HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 556, 988, 473, 57 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 556, 988, 473, 57 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 556, 988, 473, 57 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 556, 988, 473, 57 is 1.
HCF(556, 988, 473, 57) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 556, 988, 473, 57 is 1.
Step 1: Since 988 > 556, we apply the division lemma to 988 and 556, to get
988 = 556 x 1 + 432
Step 2: Since the reminder 556 ≠ 0, we apply division lemma to 432 and 556, to get
556 = 432 x 1 + 124
Step 3: We consider the new divisor 432 and the new remainder 124, and apply the division lemma to get
432 = 124 x 3 + 60
We consider the new divisor 124 and the new remainder 60,and apply the division lemma to get
124 = 60 x 2 + 4
We consider the new divisor 60 and the new remainder 4,and apply the division lemma to get
60 = 4 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 556 and 988 is 4
Notice that 4 = HCF(60,4) = HCF(124,60) = HCF(432,124) = HCF(556,432) = HCF(988,556) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 473 > 4, we apply the division lemma to 473 and 4, to get
473 = 4 x 118 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 473 is 1
Notice that 1 = HCF(4,1) = HCF(473,4) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 57 > 1, we apply the division lemma to 57 and 1, to get
57 = 1 x 57 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 57 is 1
Notice that 1 = HCF(57,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
