HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 738, 442, 565 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 738, 442, 565 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 738, 442, 565 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 738, 442, 565 is 1.
HCF(738, 442, 565) = 1
HCF of 738, 442, 565 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 738, 442, 565 is 1.
Highest Common Factor of 738,442,565 is 1
Step 1: Since 738 > 442, we apply the division lemma to 738 and 442, to get
738 = 442 x 1 + 296
Step 2: Since the reminder 442 ≠ 0, we apply division lemma to 296 and 442, to get
442 = 296 x 1 + 146
Step 3: We consider the new divisor 296 and the new remainder 146, and apply the division lemma to get
296 = 146 x 2 + 4
We consider the new divisor 146 and the new remainder 4,and apply the division lemma to get
146 = 4 x 36 + 2
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 738 and 442 is 2
Notice that 2 = HCF(4,2) = HCF(146,4) = HCF(296,146) = HCF(442,296) = HCF(738,442) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 565 > 2, we apply the division lemma to 565 and 2, to get
565 = 2 x 282 + 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 565 is 1
Notice that 1 = HCF(2,1) = HCF(565,2) .
