HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 743, 152, 206 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 743, 152, 206 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 743, 152, 206 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 743, 152, 206 is 1.
HCF(743, 152, 206) = 1
HCF of 743, 152, 206 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 743, 152, 206 is 1.
Highest Common Factor of 743,152,206 is 1
Step 1: Since 743 > 152, we apply the division lemma to 743 and 152, to get
743 = 152 x 4 + 135
Step 2: Since the reminder 152 ≠ 0, we apply division lemma to 135 and 152, to get
152 = 135 x 1 + 17
Step 3: We consider the new divisor 135 and the new remainder 17, and apply the division lemma to get
135 = 17 x 7 + 16
We consider the new divisor 17 and the new remainder 16,and apply the division lemma to get
17 = 16 x 1 + 1
We consider the new divisor 16 and the new remainder 1,and apply the division lemma to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 743 and 152 is 1
Notice that 1 = HCF(16,1) = HCF(17,16) = HCF(135,17) = HCF(152,135) = HCF(743,152) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 206 > 1, we apply the division lemma to 206 and 1, to get
206 = 1 x 206 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 206 is 1
Notice that 1 = HCF(206,1) .
