HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 921, 510 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 921, 510 is 3 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 921, 510 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 921, 510 is 3.
HCF(921, 510) = 3
HCF of 921, 510 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 921, 510 is 3.
Highest Common Factor of 921,510 is 3
Step 1: Since 921 > 510, we apply the division lemma to 921 and 510, to get
921 = 510 x 1 + 411
Step 2: Since the reminder 510 ≠ 0, we apply division lemma to 411 and 510, to get
510 = 411 x 1 + 99
Step 3: We consider the new divisor 411 and the new remainder 99, and apply the division lemma to get
411 = 99 x 4 + 15
We consider the new divisor 99 and the new remainder 15,and apply the division lemma to get
99 = 15 x 6 + 9
We consider the new divisor 15 and the new remainder 9,and apply the division lemma to get
15 = 9 x 1 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 921 and 510 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(99,15) = HCF(411,99) = HCF(510,411) = HCF(921,510) .
