GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(258, 728) = 93912
GCD(258, 728) = ( 258 x 728 ) / 93912
= 258 / 728
= 258
Step2:
LCM(2, 529) = 1058
GCD(2, 529) = ( 2 x 529 ) / 1058
= 2 / 529
= 2
Step3:
LCM(1, 785) = 785
GCD(1, 785) = ( 1 x 785 ) / 785
= 1 / 785
= 1
So, Greatest Common Divisor of 258, 728, 529, 785 is 1
