HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 559, 639 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 559, 639 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 559, 639 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 559, 639 is 1.

HCF(559, 639) = 1

HCF of 559, 639 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 559, 639 is 1.

Highest Common Factor of 559,639 using Euclid's algorithm

Highest Common Factor of 559,639 is 1

Step 1: Since 639 > 559, we apply the division lemma to 639 and 559, to get

639 = 559 x 1 + 80

Step 2: Since the reminder 559 ≠ 0, we apply division lemma to 80 and 559, to get

559 = 80 x 6 + 79

Step 3: We consider the new divisor 80 and the new remainder 79, and apply the division lemma to get

80 = 79 x 1 + 1

We consider the new divisor 79 and the new remainder 1, and apply the division lemma to get

79 = 1 x 79 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 559 and 639 is 1

Notice that 1 = HCF(79,1) = HCF(80,79) = HCF(559,80) = HCF(639,559) .
