GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(846, 243) = 22842
GCD(846, 243) = ( 846 x 243 ) / 22842
= 846 / 243
= 846
Step2:
LCM(9, 436) = 3924
GCD(9, 436) = ( 9 x 436 ) / 3924
= 9 / 436
= 9
Step3:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
So, Greatest Common Divisor of 846, 243, 436, 781 is 1
