HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 90, 194, 742, 342 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 90, 194, 742, 342 is 2 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 90, 194, 742, 342 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 90, 194, 742, 342 is 2.
HCF(90, 194, 742, 342) = 2
HCF of 90, 194, 742, 342 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 90, 194, 742, 342 is 2.
Highest Common Factor of 90,194,742,342 is 2
Step 1: Since 194 > 90, we apply the division lemma to 194 and 90, to get
194 = 90 x 2 + 14
Step 2: Since the reminder 90 ≠ 0, we apply division lemma to 14 and 90, to get
90 = 14 x 6 + 6
Step 3: We consider the new divisor 14 and the new remainder 6, and apply the division lemma to get
14 = 6 x 2 + 2
We consider the new divisor 6 and the new remainder 2, and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 90 and 194 is 2
Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(90,14) = HCF(194,90) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 742 > 2, we apply the division lemma to 742 and 2, to get
742 = 2 x 371 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 742 is 2
Notice that 2 = HCF(742,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 342 > 2, we apply the division lemma to 342 and 2, to get
342 = 2 x 171 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 342 is 2
Notice that 2 = HCF(342,2) .
