Steps to Calculate GCD of 357, 814, 81, 521 using LCM Formula
Given numbers are 357, 814, 81, 521
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(357, 814) = 290598
GCD(357, 814) = ( 357 x 814 ) / 290598
= 357 / 814
= 357
Step2:
LCM(1, 81) = 81
GCD(1, 81) = ( 1 x 81 ) / 81
= 1 / 81
= 1
Step3:
LCM(1, 521) = 521
GCD(1, 521) = ( 1 x 521 ) / 521
= 1 / 521
= 1
So, Greatest Common Divisor of 357, 814, 81, 521 is 1
