HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 684, 920 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 684, 920 is 4 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 684, 920 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 684, 920 is 4.
HCF(684, 920) = 4
HCF of 684, 920 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 684, 920 is 4.
Highest Common Factor of 684,920 is 4
Step 1: Since 920 > 684, we apply the division lemma to 920 and 684, to get
920 = 684 x 1 + 236
Step 2: Since the reminder 684 ≠ 0, we apply division lemma to 236 and 684, to get
684 = 236 x 2 + 212
Step 3: We consider the new divisor 236 and the new remainder 212, and apply the division lemma to get
236 = 212 x 1 + 24
We consider the new divisor 212 and the new remainder 24,and apply the division lemma to get
212 = 24 x 8 + 20
We consider the new divisor 24 and the new remainder 20,and apply the division lemma to get
24 = 20 x 1 + 4
We consider the new divisor 20 and the new remainder 4,and apply the division lemma to get
20 = 4 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 684 and 920 is 4
Notice that 4 = HCF(20,4) = HCF(24,20) = HCF(212,24) = HCF(236,212) = HCF(684,236) = HCF(920,684) .
