HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 749, 996, 172, 43 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 749, 996, 172, 43 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 749, 996, 172, 43 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 749, 996, 172, 43 is 1.
HCF(749, 996, 172, 43) = 1
HCF of 749, 996, 172, 43 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 749, 996, 172, 43 is 1.
Highest Common Factor of 749,996,172,43 is 1
Step 1: Since 996 > 749, we apply the division lemma to 996 and 749, to get
996 = 749 x 1 + 247
Step 2: Since the reminder 749 ≠ 0, we apply division lemma to 247 and 749, to get
749 = 247 x 3 + 8
Step 3: We consider the new divisor 247 and the new remainder 8, and apply the division lemma to get
247 = 8 x 30 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 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 749 and 996 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(247,8) = HCF(749,247) = HCF(996,749) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 172 > 1, we apply the division lemma to 172 and 1, to get
172 = 1 x 172 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 172 is 1
Notice that 1 = HCF(172,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 43 > 1, we apply the division lemma to 43 and 1, to get
43 = 1 x 43 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 43 is 1
Notice that 1 = HCF(43,1) .
