HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 929, 639, 157 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 929, 639, 157 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 929, 639, 157 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 929, 639, 157 is 1.

HCF(929, 639, 157) = 1

HCF of 929, 639, 157 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 929, 639, 157 is 1.

Highest Common Factor of 929,639,157 using Euclid's algorithm

Highest Common Factor of 929,639,157 is 1

Step 1: Since 929 > 639, we apply the division lemma to 929 and 639, to get

929 = 639 x 1 + 290

Step 2: Since the reminder 639 ≠ 0, we apply division lemma to 290 and 639, to get

639 = 290 x 2 + 59

Step 3: We consider the new divisor 290 and the new remainder 59, and apply the division lemma to get

290 = 59 x 4 + 54

We consider the new divisor 59 and the new remainder 54,and apply the division lemma to get

59 = 54 x 1 + 5

We consider the new divisor 54 and the new remainder 5,and apply the division lemma to get

54 = 5 x 10 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 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 929 and 639 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(54,5) = HCF(59,54) = HCF(290,59) = HCF(639,290) = HCF(929,639) .

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

Step 1: Since 157 > 1, we apply the division lemma to 157 and 1, to get

157 = 1 x 157 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 157 is 1

Notice that 1 = HCF(157,1) .
