HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 73, 95, 42, 651 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 73, 95, 42, 651 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, 95, 42, 651 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, 95, 42, 651 is 1.
HCF(73, 95, 42, 651) = 1
HCF of 73, 95, 42, 651 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, 95, 42, 651 is 1.
Highest Common Factor of 73,95,42,651 is 1
Step 1: Since 95 > 73, we apply the division lemma to 95 and 73, to get
95 = 73 x 1 + 22
Step 2: Since the reminder 73 ≠ 0, we apply division lemma to 22 and 73, to get
73 = 22 x 3 + 7
Step 3: We consider the new divisor 22 and the new remainder 7, and apply the division lemma to get
22 = 7 x 3 + 1
We consider the new divisor 7 and the new remainder 1, and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 73 and 95 is 1
Notice that 1 = HCF(7,1) = HCF(22,7) = HCF(73,22) = HCF(95,73) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 42 > 1, we apply the division lemma to 42 and 1, to get
42 = 1 x 42 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 42 is 1
Notice that 1 = HCF(42,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 651 > 1, we apply the division lemma to 651 and 1, to get
651 = 1 x 651 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 651 is 1
Notice that 1 = HCF(651,1) .
