Given numbers are 781, 181, 716, 489
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(781, 181) = 141361
GCD(781, 181) = ( 781 x 181 ) / 141361
= 781 / 181
= 781
Step2:
LCM(1, 716) = 716
GCD(1, 716) = ( 1 x 716 ) / 716
= 1 / 716
= 1
Step3:
LCM(1, 489) = 489
GCD(1, 489) = ( 1 x 489 ) / 489
= 1 / 489
= 1
So, Greatest Common Divisor of 781, 181, 716, 489 is 1
