GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(981, 858) = 280566
GCD(981, 858) = ( 981 x 858 ) / 280566
= 981 / 858
= 981
Step2:
LCM(3, 553) = 1659
GCD(3, 553) = ( 3 x 553 ) / 1659
= 3 / 553
= 3
Step3:
LCM(1, 893) = 893
GCD(1, 893) = ( 1 x 893 ) / 893
= 1 / 893
= 1
So, Greatest Common Divisor of 981, 858, 553, 893 is 1
