Given numbers are 143, 102, 291, 210
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(143, 102) = 14586
GCD(143, 102) = ( 143 x 102 ) / 14586
= 143 / 102
= 143
Step2:
LCM(1, 291) = 291
GCD(1, 291) = ( 1 x 291 ) / 291
= 1 / 291
= 1
Step3:
LCM(1, 210) = 210
GCD(1, 210) = ( 1 x 210 ) / 210
= 1 / 210
= 1
So, Greatest Common Divisor of 143, 102, 291, 210 is 1
