GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(975, 915) = 59475
GCD(975, 915) = ( 975 x 915 ) / 59475
= 975 / 915
= 975
Step2:
LCM(15, 198) = 990
GCD(15, 198) = ( 15 x 198 ) / 990
= 15 / 198
= 15
Step3:
LCM(3, 782) = 2346
GCD(3, 782) = ( 3 x 782 ) / 2346
= 3 / 782
= 3
So, Greatest Common Divisor of 975, 915, 198, 782 is 1
