HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 178, 490, 465 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 178, 490, 465 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 178, 490, 465 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 178, 490, 465 is 1.
HCF(178, 490, 465) = 1
HCF of 178, 490, 465 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 178, 490, 465 is 1.
Highest Common Factor of 178,490,465 is 1
Step 1: Since 490 > 178, we apply the division lemma to 490 and 178, to get
490 = 178 x 2 + 134
Step 2: Since the reminder 178 ≠ 0, we apply division lemma to 134 and 178, to get
178 = 134 x 1 + 44
Step 3: We consider the new divisor 134 and the new remainder 44, and apply the division lemma to get
134 = 44 x 3 + 2
We consider the new divisor 44 and the new remainder 2, and apply the division lemma to get
44 = 2 x 22 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 178 and 490 is 2
Notice that 2 = HCF(44,2) = HCF(134,44) = HCF(178,134) = HCF(490,178) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 465 > 2, we apply the division lemma to 465 and 2, to get
465 = 2 x 232 + 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 465 is 1
Notice that 1 = HCF(2,1) = HCF(465,2) .
