Given numbers are 616, 940, 643, 109
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(616, 940) = 144760
GCD(616, 940) = ( 616 x 940 ) / 144760
= 616 / 940
= 616
Step2:
LCM(4, 643) = 2572
GCD(4, 643) = ( 4 x 643 ) / 2572
= 4 / 643
= 4
Step3:
LCM(1, 109) = 109
GCD(1, 109) = ( 1 x 109 ) / 109
= 1 / 109
= 1
So, Greatest Common Divisor of 616, 940, 643, 109 is 1
