Given numbers are 815, 530, 98, 982
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(815, 530) = 86390
GCD(815, 530) = ( 815 x 530 ) / 86390
= 815 / 530
= 815
Step2:
LCM(5, 98) = 490
GCD(5, 98) = ( 5 x 98 ) / 490
= 5 / 98
= 5
Step3:
LCM(1, 982) = 982
GCD(1, 982) = ( 1 x 982 ) / 982
= 1 / 982
= 1
So, Greatest Common Divisor of 815, 530, 98, 982 is 1
