Given numbers are 276, 684, 977, 215
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(276, 684) = 15732
GCD(276, 684) = ( 276 x 684 ) / 15732
= 276 / 684
= 276
Step2:
LCM(12, 977) = 11724
GCD(12, 977) = ( 12 x 977 ) / 11724
= 12 / 977
= 12
Step3:
LCM(1, 215) = 215
GCD(1, 215) = ( 1 x 215 ) / 215
= 1 / 215
= 1
So, Greatest Common Divisor of 276, 684, 977, 215 is 1
