HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 660, 930 i.e. 30 the largest integer that leaves a remainder zero for all numbers.
HCF of 660, 930 is 30 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 660, 930 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 660, 930 is 30.
HCF(660, 930) = 30
HCF of 660, 930 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 660, 930 is 30.
Highest Common Factor of 660,930 is 30
Step 1: Since 930 > 660, we apply the division lemma to 930 and 660, to get
930 = 660 x 1 + 270
Step 2: Since the reminder 660 ≠ 0, we apply division lemma to 270 and 660, to get
660 = 270 x 2 + 120
Step 3: We consider the new divisor 270 and the new remainder 120, and apply the division lemma to get
270 = 120 x 2 + 30
We consider the new divisor 120 and the new remainder 30, and apply the division lemma to get
120 = 30 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 30, the HCF of 660 and 930 is 30
Notice that 30 = HCF(120,30) = HCF(270,120) = HCF(660,270) = HCF(930,660) .
