GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(357, 858) = 102102
GCD(357, 858) = ( 357 x 858 ) / 102102
= 357 / 858
= 357
Step2:
LCM(3, 625) = 1875
GCD(3, 625) = ( 3 x 625 ) / 1875
= 3 / 625
= 3
Step3:
LCM(1, 815) = 815
GCD(1, 815) = ( 1 x 815 ) / 815
= 1 / 815
= 1
So, Greatest Common Divisor of 357, 858, 625, 815 is 1
