HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 42, 86, 99, 713 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 42, 86, 99, 713 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 42, 86, 99, 713 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 42, 86, 99, 713 is 1.
HCF(42, 86, 99, 713) = 1
HCF of 42, 86, 99, 713 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 42, 86, 99, 713 is 1.
Highest Common Factor of 42,86,99,713 is 1
Step 1: Since 86 > 42, we apply the division lemma to 86 and 42, to get
86 = 42 x 2 + 2
Step 2: Since the reminder 42 ≠ 0, we apply division lemma to 2 and 42, to get
42 = 2 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 42 and 86 is 2
Notice that 2 = HCF(42,2) = HCF(86,42) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 99 > 2, we apply the division lemma to 99 and 2, to get
99 = 2 x 49 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 99 is 1
Notice that 1 = HCF(2,1) = HCF(99,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 713 > 1, we apply the division lemma to 713 and 1, to get
713 = 1 x 713 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 713 is 1
Notice that 1 = HCF(713,1) .
