Given numbers are 540, 972, 220, 947
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(540, 972) = 4860
GCD(540, 972) = ( 540 x 972 ) / 4860
= 540 / 972
= 540
Step2:
LCM(108, 220) = 5940
GCD(108, 220) = ( 108 x 220 ) / 5940
= 108 / 220
= 108
Step3:
LCM(4, 947) = 3788
GCD(4, 947) = ( 4 x 947 ) / 3788
= 4 / 947
= 4
So, Greatest Common Divisor of 540, 972, 220, 947 is 1
