HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 752, 438, 494 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 752, 438, 494 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 752, 438, 494 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 752, 438, 494 is 2.
HCF(752, 438, 494) = 2
HCF of 752, 438, 494 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 752, 438, 494 is 2.
Highest Common Factor of 752,438,494 is 2
Step 1: Since 752 > 438, we apply the division lemma to 752 and 438, to get
752 = 438 x 1 + 314
Step 2: Since the reminder 438 ≠ 0, we apply division lemma to 314 and 438, to get
438 = 314 x 1 + 124
Step 3: We consider the new divisor 314 and the new remainder 124, and apply the division lemma to get
314 = 124 x 2 + 66
We consider the new divisor 124 and the new remainder 66,and apply the division lemma to get
124 = 66 x 1 + 58
We consider the new divisor 66 and the new remainder 58,and apply the division lemma to get
66 = 58 x 1 + 8
We consider the new divisor 58 and the new remainder 8,and apply the division lemma to get
58 = 8 x 7 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 752 and 438 is 2
Notice that 2 = HCF(8,2) = HCF(58,8) = HCF(66,58) = HCF(124,66) = HCF(314,124) = HCF(438,314) = HCF(752,438) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 494 > 2, we apply the division lemma to 494 and 2, to get
494 = 2 x 247 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 494 is 2
Notice that 2 = HCF(494,2) .
