HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 423, 739, 802 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 423, 739, 802 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 423, 739, 802 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 423, 739, 802 is 1.
HCF(423, 739, 802) = 1
HCF of 423, 739, 802 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 423, 739, 802 is 1.
Highest Common Factor of 423,739,802 is 1
Step 1: Since 739 > 423, we apply the division lemma to 739 and 423, to get
739 = 423 x 1 + 316
Step 2: Since the reminder 423 ≠ 0, we apply division lemma to 316 and 423, to get
423 = 316 x 1 + 107
Step 3: We consider the new divisor 316 and the new remainder 107, and apply the division lemma to get
316 = 107 x 2 + 102
We consider the new divisor 107 and the new remainder 102,and apply the division lemma to get
107 = 102 x 1 + 5
We consider the new divisor 102 and the new remainder 5,and apply the division lemma to get
102 = 5 x 20 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 423 and 739 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(102,5) = HCF(107,102) = HCF(316,107) = HCF(423,316) = HCF(739,423) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 802 > 1, we apply the division lemma to 802 and 1, to get
802 = 1 x 802 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 802 is 1
Notice that 1 = HCF(802,1) .
