Steps to Calculate GCD of 397, 814, 807, 220 using LCM Formula
Given numbers are 397, 814, 807, 220
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(397, 814) = 323158
GCD(397, 814) = ( 397 x 814 ) / 323158
= 397 / 814
= 397
Step2:
LCM(1, 807) = 807
GCD(1, 807) = ( 1 x 807 ) / 807
= 1 / 807
= 1
Step3:
LCM(1, 220) = 220
GCD(1, 220) = ( 1 x 220 ) / 220
= 1 / 220
= 1
So, Greatest Common Divisor of 397, 814, 807, 220 is 1
