HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 70, 489, 836 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 70, 489, 836 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 70, 489, 836 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 70, 489, 836 is 1.

HCF(70, 489, 836) = 1

HCF of 70, 489, 836 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 70, 489, 836 is 1.

Highest Common Factor of 70,489,836 using Euclid's algorithm

Highest Common Factor of 70,489,836 is 1

Step 1: Since 489 > 70, we apply the division lemma to 489 and 70, to get

489 = 70 x 6 + 69

Step 2: Since the reminder 70 ≠ 0, we apply division lemma to 69 and 70, to get

70 = 69 x 1 + 1

Step 3: We consider the new divisor 69 and the new remainder 1, and apply the division lemma to get

69 = 1 x 69 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 70 and 489 is 1

Notice that 1 = HCF(69,1) = HCF(70,69) = HCF(489,70) .


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

Step 1: Since 836 > 1, we apply the division lemma to 836 and 1, to get

836 = 1 x 836 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 836 is 1

Notice that 1 = HCF(836,1) .
