Given numbers are 780, 100, 882, 544
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 100) = 3900
GCD(780, 100) = ( 780 x 100 ) / 3900
= 780 / 100
= 780
Step2:
LCM(20, 882) = 8820
GCD(20, 882) = ( 20 x 882 ) / 8820
= 20 / 882
= 20
Step3:
LCM(2, 544) = 544
GCD(2, 544) = ( 2 x 544 ) / 544
= 2 / 544
= 2
So, Greatest Common Divisor of 780, 100, 882, 544 is 2
