Given numbers are 220, 780, 594, 247
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(220, 780) = 8580
GCD(220, 780) = ( 220 x 780 ) / 8580
= 220 / 780
= 220
Step2:
LCM(20, 594) = 5940
GCD(20, 594) = ( 20 x 594 ) / 5940
= 20 / 594
= 20
Step3:
LCM(2, 247) = 494
GCD(2, 247) = ( 2 x 247 ) / 494
= 2 / 247
= 2
So, Greatest Common Divisor of 220, 780, 594, 247 is 1
