HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 639, 531, 604 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 639, 531, 604 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 639, 531, 604 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 639, 531, 604 is 1.
HCF(639, 531, 604) = 1
HCF of 639, 531, 604 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 639, 531, 604 is 1.
Highest Common Factor of 639,531,604 is 1
Step 1: Since 639 > 531, we apply the division lemma to 639 and 531, to get
639 = 531 x 1 + 108
Step 2: Since the reminder 531 ≠ 0, we apply division lemma to 108 and 531, to get
531 = 108 x 4 + 99
Step 3: We consider the new divisor 108 and the new remainder 99, and apply the division lemma to get
108 = 99 x 1 + 9
We consider the new divisor 99 and the new remainder 9, and apply the division lemma to get
99 = 9 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 639 and 531 is 9
Notice that 9 = HCF(99,9) = HCF(108,99) = HCF(531,108) = HCF(639,531) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 604 > 9, we apply the division lemma to 604 and 9, to get
604 = 9 x 67 + 1
Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 1 and 9, to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 9 and 604 is 1
Notice that 1 = HCF(9,1) = HCF(604,9) .
