Given numbers are 780, 105, 219, 187
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 105) = 5460
GCD(780, 105) = ( 780 x 105 ) / 5460
= 780 / 105
= 780
Step2:
LCM(15, 219) = 1095
GCD(15, 219) = ( 15 x 219 ) / 1095
= 15 / 219
= 15
Step3:
LCM(3, 187) = 561
GCD(3, 187) = ( 3 x 187 ) / 561
= 3 / 187
= 3
So, Greatest Common Divisor of 780, 105, 219, 187 is 1
