HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 656, 992, 165 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 656, 992, 165 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 656, 992, 165 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 656, 992, 165 is 1.
HCF(656, 992, 165) = 1
HCF of 656, 992, 165 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 656, 992, 165 is 1.
Highest Common Factor of 656,992,165 is 1
Step 1: Since 992 > 656, we apply the division lemma to 992 and 656, to get
992 = 656 x 1 + 336
Step 2: Since the reminder 656 ≠ 0, we apply division lemma to 336 and 656, to get
656 = 336 x 1 + 320
Step 3: We consider the new divisor 336 and the new remainder 320, and apply the division lemma to get
336 = 320 x 1 + 16
We consider the new divisor 320 and the new remainder 16, and apply the division lemma to get
320 = 16 x 20 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 16, the HCF of 656 and 992 is 16
Notice that 16 = HCF(320,16) = HCF(336,320) = HCF(656,336) = HCF(992,656) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 165 > 16, we apply the division lemma to 165 and 16, to get
165 = 16 x 10 + 5
Step 2: Since the reminder 16 ≠ 0, we apply division lemma to 5 and 16, to get
16 = 5 x 3 + 1
Step 3: We consider the new divisor 5 and the new remainder 1, and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 16 and 165 is 1
Notice that 1 = HCF(5,1) = HCF(16,5) = HCF(165,16) .
