Given numbers are 764, 697, 520, 491
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(764, 697) = 532508
GCD(764, 697) = ( 764 x 697 ) / 532508
= 764 / 697
= 764
Step2:
LCM(1, 520) = 520
GCD(1, 520) = ( 1 x 520 ) / 520
= 1 / 520
= 1
Step3:
LCM(1, 491) = 491
GCD(1, 491) = ( 1 x 491 ) / 491
= 1 / 491
= 1
So, Greatest Common Divisor of 764, 697, 520, 491 is 1
