HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 490, 924, 144 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 490, 924, 144 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 490, 924, 144 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 490, 924, 144 is 2.
HCF(490, 924, 144) = 2
HCF of 490, 924, 144 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 490, 924, 144 is 2.
Highest Common Factor of 490,924,144 is 2
Step 1: Since 924 > 490, we apply the division lemma to 924 and 490, to get
924 = 490 x 1 + 434
Step 2: Since the reminder 490 ≠ 0, we apply division lemma to 434 and 490, to get
490 = 434 x 1 + 56
Step 3: We consider the new divisor 434 and the new remainder 56, and apply the division lemma to get
434 = 56 x 7 + 42
We consider the new divisor 56 and the new remainder 42,and apply the division lemma to get
56 = 42 x 1 + 14
We consider the new divisor 42 and the new remainder 14,and apply the division lemma to get
42 = 14 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 490 and 924 is 14
Notice that 14 = HCF(42,14) = HCF(56,42) = HCF(434,56) = HCF(490,434) = HCF(924,490) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 144 > 14, we apply the division lemma to 144 and 14, to get
144 = 14 x 10 + 4
Step 2: Since the reminder 14 ≠ 0, we apply division lemma to 4 and 14, to get
14 = 4 x 3 + 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 14 and 144 is 2
Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(144,14) .
