HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 399, 285, 739 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 399, 285, 739 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 399, 285, 739 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 399, 285, 739 is 1.
HCF(399, 285, 739) = 1
HCF of 399, 285, 739 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 399, 285, 739 is 1.
Highest Common Factor of 399,285,739 is 1
Step 1: Since 399 > 285, we apply the division lemma to 399 and 285, to get
399 = 285 x 1 + 114
Step 2: Since the reminder 285 ≠ 0, we apply division lemma to 114 and 285, to get
285 = 114 x 2 + 57
Step 3: We consider the new divisor 114 and the new remainder 57, and apply the division lemma to get
114 = 57 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 57, the HCF of 399 and 285 is 57
Notice that 57 = HCF(114,57) = HCF(285,114) = HCF(399,285) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 739 > 57, we apply the division lemma to 739 and 57, to get
739 = 57 x 12 + 55
Step 2: Since the reminder 57 ≠ 0, we apply division lemma to 55 and 57, to get
57 = 55 x 1 + 2
Step 3: We consider the new divisor 55 and the new remainder 2, and apply the division lemma to get
55 = 2 x 27 + 1
We consider the new divisor 2 and the new remainder 1, and apply the division lemma 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 57 and 739 is 1
Notice that 1 = HCF(2,1) = HCF(55,2) = HCF(57,55) = HCF(739,57) .
