HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 109, 742, 313, 909 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 109, 742, 313, 909 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 109, 742, 313, 909 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 109, 742, 313, 909 is 1.

HCF(109, 742, 313, 909) = 1

Highest Common Factor of 109,742,313,909 using Euclid's algorithm

Highest Common Factor of 109,742,313,909 is 1

Step 1: Since 742 > 109, we apply the division lemma to 742 and 109, to get

742 = 109 x 6 + 88

Step 2: Since the reminder 109 ≠ 0, we apply division lemma to 88 and 109, to get

109 = 88 x 1 + 21

Step 3: We consider the new divisor 88 and the new remainder 21, and apply the division lemma to get

88 = 21 x 4 + 4

We consider the new divisor 21 and the new remainder 4,and apply the division lemma to get

21 = 4 x 5 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 109 and 742 is 1

Notice that 1 = HCF(4,1) = HCF(21,4) = HCF(88,21) = HCF(109,88) = HCF(742,109) .


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

Step 1: Since 313 > 1, we apply the division lemma to 313 and 1, to get

313 = 1 x 313 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 313 is 1

Notice that 1 = HCF(313,1) .


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

Step 1: Since 909 > 1, we apply the division lemma to 909 and 1, to get

909 = 1 x 909 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 909 is 1

Notice that 1 = HCF(909,1) .
