GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(915, 781) = 714615
GCD(915, 781) = ( 915 x 781 ) / 714615
= 915 / 781
= 915
Step2:
LCM(1, 436) = 436
GCD(1, 436) = ( 1 x 436 ) / 436
= 1 / 436
= 1
Step3:
LCM(1, 496) = 496
GCD(1, 496) = ( 1 x 496 ) / 496
= 1 / 496
= 1
So, Greatest Common Divisor of 915, 781, 436, 496 is 1
