HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 137, 421, 840, 710 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 137, 421, 840, 710 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 137, 421, 840, 710 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 137, 421, 840, 710 is 1.

HCF(137, 421, 840, 710) = 1

Highest Common Factor of 137,421,840,710 using Euclid's algorithm

Highest Common Factor of 137,421,840,710 is 1

Step 1: Since 421 > 137, we apply the division lemma to 421 and 137, to get

421 = 137 x 3 + 10

Step 2: Since the reminder 137 ≠ 0, we apply division lemma to 10 and 137, to get

137 = 10 x 13 + 7

Step 3: We consider the new divisor 10 and the new remainder 7, and apply the division lemma to get

10 = 7 x 1 + 3

We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get

7 = 3 x 2 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 137 and 421 is 1

Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(137,10) = HCF(421,137) .


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

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

840 = 1 x 840 + 0

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

Notice that 1 = HCF(840,1) .


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

Step 1: Since 710 > 1, we apply the division lemma to 710 and 1, to get

710 = 1 x 710 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 710 is 1

Notice that 1 = HCF(710,1) .
