HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 73, 99, 52, 781 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 73, 99, 52, 781 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 73, 99, 52, 781 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 73, 99, 52, 781 is 1.
HCF(73, 99, 52, 781) = 1
HCF of 73, 99, 52, 781 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 73, 99, 52, 781 is 1.
Highest Common Factor of 73,99,52,781 is 1
Step 1: Since 99 > 73, we apply the division lemma to 99 and 73, to get
99 = 73 x 1 + 26
Step 2: Since the reminder 73 ≠ 0, we apply division lemma to 26 and 73, to get
73 = 26 x 2 + 21
Step 3: We consider the new divisor 26 and the new remainder 21, and apply the division lemma to get
26 = 21 x 1 + 5
We consider the new divisor 21 and the new remainder 5,and apply the division lemma to get
21 = 5 x 4 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 73 and 99 is 1
Notice that 1 = HCF(5,1) = HCF(21,5) = HCF(26,21) = HCF(73,26) = HCF(99,73) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 52 > 1, we apply the division lemma to 52 and 1, to get
52 = 1 x 52 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 52 is 1
Notice that 1 = HCF(52,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 781 > 1, we apply the division lemma to 781 and 1, to get
781 = 1 x 781 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 781 is 1
Notice that 1 = HCF(781,1) .
