HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 709, 840, 136, 274 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 709, 840, 136, 274 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 709, 840, 136, 274 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 709, 840, 136, 274 is 1.

HCF(709, 840, 136, 274) = 1

Highest Common Factor of 709,840,136,274 using Euclid's algorithm

Highest Common Factor of 709,840,136,274 is 1

Step 1: Since 840 > 709, we apply the division lemma to 840 and 709, to get

840 = 709 x 1 + 131

Step 2: Since the reminder 709 ≠ 0, we apply division lemma to 131 and 709, to get

709 = 131 x 5 + 54

Step 3: We consider the new divisor 131 and the new remainder 54, and apply the division lemma to get

131 = 54 x 2 + 23

We consider the new divisor 54 and the new remainder 23,and apply the division lemma to get

54 = 23 x 2 + 8

We consider the new divisor 23 and the new remainder 8,and apply the division lemma to get

23 = 8 x 2 + 7

We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get

8 = 7 x 1 + 1

We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get

7 = 1 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 709 and 840 is 1

Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(23,8) = HCF(54,23) = HCF(131,54) = HCF(709,131) = HCF(840,709) .


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

Step 1: Since 136 > 1, we apply the division lemma to 136 and 1, to get

136 = 1 x 136 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 136 is 1

Notice that 1 = HCF(136,1) .


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

Step 1: Since 274 > 1, we apply the division lemma to 274 and 1, to get

274 = 1 x 274 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 274 is 1

Notice that 1 = HCF(274,1) .
