GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(858, 412) = 176748
GCD(858, 412) = ( 858 x 412 ) / 176748
= 858 / 412
= 858
Step2:
LCM(2, 243) = 486
GCD(2, 243) = ( 2 x 243 ) / 486
= 2 / 243
= 2
Step3:
LCM(1, 357) = 357
GCD(1, 357) = ( 1 x 357 ) / 357
= 1 / 357
= 1
So, Greatest Common Divisor of 858, 412, 243, 357 is 1
