Given numbers are 654, 286, 532, 689
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(654, 286) = 93522
GCD(654, 286) = ( 654 x 286 ) / 93522
= 654 / 286
= 654
Step2:
LCM(2, 532) = 532
GCD(2, 532) = ( 2 x 532 ) / 532
= 2 / 532
= 2
Step3:
LCM(2, 689) = 1378
GCD(2, 689) = ( 2 x 689 ) / 1378
= 2 / 689
= 2
So, Greatest Common Divisor of 654, 286, 532, 689 is 1
