GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(786, 915) = 239730
GCD(786, 915) = ( 786 x 915 ) / 239730
= 786 / 915
= 786
Step2:
LCM(3, 705) = 705
GCD(3, 705) = ( 3 x 705 ) / 705
= 3 / 705
= 3
Step3:
LCM(3, 498) = 498
GCD(3, 498) = ( 3 x 498 ) / 498
= 3 / 498
= 3
So, Greatest Common Divisor of 786, 915, 705, 498 is 3
