Given numbers are 491, 840, 408, 763
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(491, 840) = 412440
GCD(491, 840) = ( 491 x 840 ) / 412440
= 491 / 840
= 491
Step2:
LCM(1, 408) = 408
GCD(1, 408) = ( 1 x 408 ) / 408
= 1 / 408
= 1
Step3:
LCM(1, 763) = 763
GCD(1, 763) = ( 1 x 763 ) / 763
= 1 / 763
= 1
So, Greatest Common Divisor of 491, 840, 408, 763 is 1
