HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 648, 896, 680 i.e. 8 the largest integer that leaves a remainder zero for all numbers.

HCF of 648, 896, 680 is 8 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 648, 896, 680 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 648, 896, 680 is 8.

HCF(648, 896, 680) = 8

HCF of 648, 896, 680 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 648, 896, 680 is 8.

Highest Common Factor of 648,896,680 using Euclid's algorithm

Highest Common Factor of 648,896,680 is 8

Step 1: Since 896 > 648, we apply the division lemma to 896 and 648, to get

896 = 648 x 1 + 248

Step 2: Since the reminder 648 ≠ 0, we apply division lemma to 248 and 648, to get

648 = 248 x 2 + 152

Step 3: We consider the new divisor 248 and the new remainder 152, and apply the division lemma to get

248 = 152 x 1 + 96

We consider the new divisor 152 and the new remainder 96,and apply the division lemma to get

152 = 96 x 1 + 56

We consider the new divisor 96 and the new remainder 56,and apply the division lemma to get

96 = 56 x 1 + 40

We consider the new divisor 56 and the new remainder 40,and apply the division lemma to get

56 = 40 x 1 + 16

We consider the new divisor 40 and the new remainder 16,and apply the division lemma to get

40 = 16 x 2 + 8

We consider the new divisor 16 and the new remainder 8,and apply the division lemma to get

16 = 8 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 648 and 896 is 8

Notice that 8 = HCF(16,8) = HCF(40,16) = HCF(56,40) = HCF(96,56) = HCF(152,96) = HCF(248,152) = HCF(648,248) = HCF(896,648) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 680 > 8, we apply the division lemma to 680 and 8, to get

680 = 8 x 85 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 8 and 680 is 8

Notice that 8 = HCF(680,8) .
