Given numbers are 840, 912, 352, 220
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 912) = 31920
GCD(840, 912) = ( 840 x 912 ) / 31920
= 840 / 912
= 840
Step2:
LCM(24, 352) = 1056
GCD(24, 352) = ( 24 x 352 ) / 1056
= 24 / 352
= 24
Step3:
LCM(8, 220) = 440
GCD(8, 220) = ( 8 x 220 ) / 440
= 8 / 220
= 8
So, Greatest Common Divisor of 840, 912, 352, 220 is 4
