Given numbers are 921, 312, 543, 781
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(921, 312) = 95784
GCD(921, 312) = ( 921 x 312 ) / 95784
= 921 / 312
= 921
Step2:
LCM(3, 543) = 543
GCD(3, 543) = ( 3 x 543 ) / 543
= 3 / 543
= 3
Step3:
LCM(3, 781) = 2343
GCD(3, 781) = ( 3 x 781 ) / 2343
= 3 / 781
= 3
So, Greatest Common Divisor of 921, 312, 543, 781 is 1
