Given numbers are 614, 921, 532, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(614, 921) = 1842
GCD(614, 921) = ( 614 x 921 ) / 1842
= 614 / 921
= 614
Step2:
LCM(307, 532) = 163324
GCD(307, 532) = ( 307 x 532 ) / 163324
= 307 / 532
= 307
Step3:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 614, 921, 532, 420 is 1
