HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 74, 203, 545 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 74, 203, 545 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 74, 203, 545 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 74, 203, 545 is 1.
HCF(74, 203, 545) = 1
HCF of 74, 203, 545 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 74, 203, 545 is 1.
Highest Common Factor of 74,203,545 is 1
Step 1: Since 203 > 74, we apply the division lemma to 203 and 74, to get
203 = 74 x 2 + 55
Step 2: Since the reminder 74 ≠ 0, we apply division lemma to 55 and 74, to get
74 = 55 x 1 + 19
Step 3: We consider the new divisor 55 and the new remainder 19, and apply the division lemma to get
55 = 19 x 2 + 17
We consider the new divisor 19 and the new remainder 17,and apply the division lemma to get
19 = 17 x 1 + 2
We consider the new divisor 17 and the new remainder 2,and apply the division lemma to get
17 = 2 x 8 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 74 and 203 is 1
Notice that 1 = HCF(2,1) = HCF(17,2) = HCF(19,17) = HCF(55,19) = HCF(74,55) = HCF(203,74) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 545 > 1, we apply the division lemma to 545 and 1, to get
545 = 1 x 545 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 545 is 1
Notice that 1 = HCF(545,1) .
