Given numbers are 858, 542, 286, 197
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(858, 542) = 232518
GCD(858, 542) = ( 858 x 542 ) / 232518
= 858 / 542
= 858
Step2:
LCM(2, 286) = 286
GCD(2, 286) = ( 2 x 286 ) / 286
= 2 / 286
= 2
Step3:
LCM(2, 197) = 394
GCD(2, 197) = ( 2 x 197 ) / 394
= 2 / 197
= 2
So, Greatest Common Divisor of 858, 542, 286, 197 is 1
