HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 98, 666, 673 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 98, 666, 673 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 98, 666, 673 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 98, 666, 673 is 1.

HCF(98, 666, 673) = 1

Highest common factor (HCF) of 98, 666, 673 is 1.

Highest Common Factor of 98,666,673 using Euclid's algorithm

Highest Common Factor of 98,666,673 is 1

Step 1: Since 666 > 98, we apply the division lemma to 666 and 98, to get

666 = 98 x 6 + 78

Step 2: Since the reminder 98 ≠ 0, we apply division lemma to 78 and 98, to get

98 = 78 x 1 + 20

Step 3: We consider the new divisor 78 and the new remainder 20, and apply the division lemma to get

78 = 20 x 3 + 18

We consider the new divisor 20 and the new remainder 18,and apply the division lemma to get

20 = 18 x 1 + 2

We consider the new divisor 18 and the new remainder 2,and apply the division lemma to get

18 = 2 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 98 and 666 is 2

Notice that 2 = HCF(18,2) = HCF(20,18) = HCF(78,20) = HCF(98,78) = HCF(666,98) .


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

Step 1: Since 673 > 2, we apply the division lemma to 673 and 2, to get

673 = 2 x 336 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 673 is 1

Notice that 1 = HCF(2,1) = HCF(673,2) .
