HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 552, 198, 73 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 552, 198, 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 552, 198, 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 552, 198, 73 is 1.
HCF(552, 198, 73) = 1
HCF of 552, 198, 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 552, 198, 73 is 1.
Highest Common Factor of 552,198,73 is 1
Step 1: Since 552 > 198, we apply the division lemma to 552 and 198, to get
552 = 198 x 2 + 156
Step 2: Since the reminder 198 ≠ 0, we apply division lemma to 156 and 198, to get
198 = 156 x 1 + 42
Step 3: We consider the new divisor 156 and the new remainder 42, and apply the division lemma to get
156 = 42 x 3 + 30
We consider the new divisor 42 and the new remainder 30,and apply the division lemma to get
42 = 30 x 1 + 12
We consider the new divisor 30 and the new remainder 12,and apply the division lemma to get
30 = 12 x 2 + 6
We consider the new divisor 12 and the new remainder 6,and apply the division lemma to get
12 = 6 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 552 and 198 is 6
Notice that 6 = HCF(12,6) = HCF(30,12) = HCF(42,30) = HCF(156,42) = HCF(198,156) = HCF(552,198) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 73 > 6, we apply the division lemma to 73 and 6, to get
73 = 6 x 12 + 1
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 1 and 6, to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 6 and 73 is 1
Notice that 1 = HCF(6,1) = HCF(73,6) .
