HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 436, 680 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 436, 680 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 436, 680 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 436, 680 is 4.
HCF(436, 680) = 4
HCF of 436, 680 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 436, 680 is 4.
Highest Common Factor of 436,680 is 4
Step 1: Since 680 > 436, we apply the division lemma to 680 and 436, to get
680 = 436 x 1 + 244
Step 2: Since the reminder 436 ≠ 0, we apply division lemma to 244 and 436, to get
436 = 244 x 1 + 192
Step 3: We consider the new divisor 244 and the new remainder 192, and apply the division lemma to get
244 = 192 x 1 + 52
We consider the new divisor 192 and the new remainder 52,and apply the division lemma to get
192 = 52 x 3 + 36
We consider the new divisor 52 and the new remainder 36,and apply the division lemma to get
52 = 36 x 1 + 16
We consider the new divisor 36 and the new remainder 16,and apply the division lemma to get
36 = 16 x 2 + 4
We consider the new divisor 16 and the new remainder 4,and apply the division lemma to get
16 = 4 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 436 and 680 is 4
Notice that 4 = HCF(16,4) = HCF(36,16) = HCF(52,36) = HCF(192,52) = HCF(244,192) = HCF(436,244) = HCF(680,436) .
