HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 656, 176, 558 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 656, 176, 558 is 2 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, 176, 558 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, 176, 558 is 2.
HCF(656, 176, 558) = 2
HCF of 656, 176, 558 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, 176, 558 is 2.
Highest Common Factor of 656,176,558 is 2
Step 1: Since 656 > 176, we apply the division lemma to 656 and 176, to get
656 = 176 x 3 + 128
Step 2: Since the reminder 176 ≠ 0, we apply division lemma to 128 and 176, to get
176 = 128 x 1 + 48
Step 3: We consider the new divisor 128 and the new remainder 48, and apply the division lemma to get
128 = 48 x 2 + 32
We consider the new divisor 48 and the new remainder 32,and apply the division lemma to get
48 = 32 x 1 + 16
We consider the new divisor 32 and the new remainder 16,and apply the division lemma to get
32 = 16 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 16, the HCF of 656 and 176 is 16
Notice that 16 = HCF(32,16) = HCF(48,32) = HCF(128,48) = HCF(176,128) = HCF(656,176) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 558 > 16, we apply the division lemma to 558 and 16, to get
558 = 16 x 34 + 14
Step 2: Since the reminder 16 ≠ 0, we apply division lemma to 14 and 16, to get
16 = 14 x 1 + 2
Step 3: We consider the new divisor 14 and the new remainder 2, and apply the division lemma to get
14 = 2 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 16 and 558 is 2
Notice that 2 = HCF(14,2) = HCF(16,14) = HCF(558,16) .
