HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 648, 65970 i.e. 18 the largest integer that leaves a remainder zero for all numbers.
HCF of 648, 65970 is 18 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 648, 65970 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 648, 65970 is 18.
HCF(648, 65970) = 18
HCF of 648, 65970 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 648, 65970 is 18.
Highest Common Factor of 648,65970 is 18
Step 1: Since 65970 > 648, we apply the division lemma to 65970 and 648, to get
65970 = 648 x 101 + 522
Step 2: Since the reminder 648 ≠ 0, we apply division lemma to 522 and 648, to get
648 = 522 x 1 + 126
Step 3: We consider the new divisor 522 and the new remainder 126, and apply the division lemma to get
522 = 126 x 4 + 18
We consider the new divisor 126 and the new remainder 18, and apply the division lemma to get
126 = 18 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 648 and 65970 is 18
Notice that 18 = HCF(126,18) = HCF(522,126) = HCF(648,522) = HCF(65970,648) .
