HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 388, 566, 556, 73 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 388, 566, 556, 73 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 388, 566, 556, 73 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 388, 566, 556, 73 is 1.
HCF(388, 566, 556, 73) = 1
HCF of 388, 566, 556, 73 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 388, 566, 556, 73 is 1.
Highest Common Factor of 388,566,556,73 is 1
Step 1: Since 566 > 388, we apply the division lemma to 566 and 388, to get
566 = 388 x 1 + 178
Step 2: Since the reminder 388 ≠ 0, we apply division lemma to 178 and 388, to get
388 = 178 x 2 + 32
Step 3: We consider the new divisor 178 and the new remainder 32, and apply the division lemma to get
178 = 32 x 5 + 18
We consider the new divisor 32 and the new remainder 18,and apply the division lemma to get
32 = 18 x 1 + 14
We consider the new divisor 18 and the new remainder 14,and apply the division lemma to get
18 = 14 x 1 + 4
We consider the new divisor 14 and the new remainder 4,and apply the division lemma to get
14 = 4 x 3 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 388 and 566 is 2
Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(18,14) = HCF(32,18) = HCF(178,32) = HCF(388,178) = HCF(566,388) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 556 > 2, we apply the division lemma to 556 and 2, to get
556 = 2 x 278 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 556 is 2
Notice that 2 = HCF(556,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 73 > 2, we apply the division lemma to 73 and 2, to get
73 = 2 x 36 + 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 73 is 1
Notice that 1 = HCF(2,1) = HCF(73,2) .
