GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(153, 987) = 50337
GCD(153, 987) = ( 153 x 987 ) / 50337
= 153 / 987
= 153
Step2:
LCM(3, 859) = 2577
GCD(3, 859) = ( 3 x 859 ) / 2577
= 3 / 859
= 3
Step3:
LCM(1, 243) = 243
GCD(1, 243) = ( 1 x 243 ) / 243
= 1 / 243
= 1
So, Greatest Common Divisor of 153, 987, 859, 243 is 1
