HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 782, 165, 354 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 782, 165, 354 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 782, 165, 354 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 782, 165, 354 is 1.
HCF(782, 165, 354) = 1
HCF of 782, 165, 354 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 782, 165, 354 is 1.
Highest Common Factor of 782,165,354 is 1
Step 1: Since 782 > 165, we apply the division lemma to 782 and 165, to get
782 = 165 x 4 + 122
Step 2: Since the reminder 165 ≠ 0, we apply division lemma to 122 and 165, to get
165 = 122 x 1 + 43
Step 3: We consider the new divisor 122 and the new remainder 43, and apply the division lemma to get
122 = 43 x 2 + 36
We consider the new divisor 43 and the new remainder 36,and apply the division lemma to get
43 = 36 x 1 + 7
We consider the new divisor 36 and the new remainder 7,and apply the division lemma to get
36 = 7 x 5 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 782 and 165 is 1
Notice that 1 = HCF(7,1) = HCF(36,7) = HCF(43,36) = HCF(122,43) = HCF(165,122) = HCF(782,165) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 354 > 1, we apply the division lemma to 354 and 1, to get
354 = 1 x 354 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 354 is 1
Notice that 1 = HCF(354,1) .
