HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 124, 702, 80, 349 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 124, 702, 80, 349 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 124, 702, 80, 349 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 124, 702, 80, 349 is 1.

HCF(124, 702, 80, 349) = 1

Highest Common Factor of 124,702,80,349 using Euclid's algorithm

Highest Common Factor of 124,702,80,349 is 1

Step 1: Since 702 > 124, we apply the division lemma to 702 and 124, to get

702 = 124 x 5 + 82

Step 2: Since the reminder 124 ≠ 0, we apply division lemma to 82 and 124, to get

124 = 82 x 1 + 42

Step 3: We consider the new divisor 82 and the new remainder 42, and apply the division lemma to get

82 = 42 x 1 + 40

We consider the new divisor 42 and the new remainder 40,and apply the division lemma to get

42 = 40 x 1 + 2

We consider the new divisor 40 and the new remainder 2,and apply the division lemma to get

40 = 2 x 20 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 124 and 702 is 2

Notice that 2 = HCF(40,2) = HCF(42,40) = HCF(82,42) = HCF(124,82) = HCF(702,124) .


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

Step 1: Since 80 > 2, we apply the division lemma to 80 and 2, to get

80 = 2 x 40 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 80 is 2

Notice that 2 = HCF(80,2) .


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

Step 1: Since 349 > 2, we apply the division lemma to 349 and 2, to get

349 = 2 x 174 + 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 349 is 1

Notice that 1 = HCF(2,1) = HCF(349,2) .
