HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 118, 691, 496, 73 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 118, 691, 496, 73 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 118, 691, 496, 73 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 118, 691, 496, 73 is 1.
HCF(118, 691, 496, 73) = 1
HCF of 118, 691, 496, 73 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 118, 691, 496, 73 is 1.
Highest Common Factor of 118,691,496,73 is 1
Step 1: Since 691 > 118, we apply the division lemma to 691 and 118, to get
691 = 118 x 5 + 101
Step 2: Since the reminder 118 ≠ 0, we apply division lemma to 101 and 118, to get
118 = 101 x 1 + 17
Step 3: We consider the new divisor 101 and the new remainder 17, and apply the division lemma to get
101 = 17 x 5 + 16
We consider the new divisor 17 and the new remainder 16,and apply the division lemma to get
17 = 16 x 1 + 1
We consider the new divisor 16 and the new remainder 1,and apply the division lemma to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 118 and 691 is 1
Notice that 1 = HCF(16,1) = HCF(17,16) = HCF(101,17) = HCF(118,101) = HCF(691,118) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 496 > 1, we apply the division lemma to 496 and 1, to get
496 = 1 x 496 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 496 is 1
Notice that 1 = HCF(496,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 73 > 1, we apply the division lemma to 73 and 1, to get
73 = 1 x 73 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 73 is 1
Notice that 1 = HCF(73,1) .
