Given numbers are 807, 915, 491, 355
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(807, 915) = 246135
GCD(807, 915) = ( 807 x 915 ) / 246135
= 807 / 915
= 807
Step2:
LCM(3, 491) = 1473
GCD(3, 491) = ( 3 x 491 ) / 1473
= 3 / 491
= 3
Step3:
LCM(1, 355) = 355
GCD(1, 355) = ( 1 x 355 ) / 355
= 1 / 355
= 1
So, Greatest Common Divisor of 807, 915, 491, 355 is 1
