GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(747, 940) = 702180
GCD(747, 940) = ( 747 x 940 ) / 702180
= 747 / 940
= 747
Step2:
LCM(1, 817) = 817
GCD(1, 817) = ( 1 x 817 ) / 817
= 1 / 817
= 1
Step3:
LCM(1, 258) = 258
GCD(1, 258) = ( 1 x 258 ) / 258
= 1 / 258
= 1
So, Greatest Common Divisor of 747, 940, 817, 258 is 1
