HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 690, 162, 298 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 690, 162, 298 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 690, 162, 298 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 690, 162, 298 is 2.
HCF(690, 162, 298) = 2
HCF of 690, 162, 298 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 690, 162, 298 is 2.
Highest Common Factor of 690,162,298 is 2
Step 1: Since 690 > 162, we apply the division lemma to 690 and 162, to get
690 = 162 x 4 + 42
Step 2: Since the reminder 162 ≠ 0, we apply division lemma to 42 and 162, to get
162 = 42 x 3 + 36
Step 3: We consider the new divisor 42 and the new remainder 36, and apply the division lemma to get
42 = 36 x 1 + 6
We consider the new divisor 36 and the new remainder 6, and apply the division lemma to get
36 = 6 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 690 and 162 is 6
Notice that 6 = HCF(36,6) = HCF(42,36) = HCF(162,42) = HCF(690,162) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 298 > 6, we apply the division lemma to 298 and 6, to get
298 = 6 x 49 + 4
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 4 and 6, to get
6 = 4 x 1 + 2
Step 3: We consider the new divisor 4 and the new remainder 2, and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 6 and 298 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(298,6) .
