Given numbers are 641, 966, 458, 549
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(641, 966) = 619206
GCD(641, 966) = ( 641 x 966 ) / 619206
= 641 / 966
= 641
Step2:
LCM(1, 458) = 458
GCD(1, 458) = ( 1 x 458 ) / 458
= 1 / 458
= 1
Step3:
LCM(1, 549) = 549
GCD(1, 549) = ( 1 x 549 ) / 549
= 1 / 549
= 1
So, Greatest Common Divisor of 641, 966, 458, 549 is 1
