Given numbers are 924, 290, 647, 221
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(924, 290) = 133980
GCD(924, 290) = ( 924 x 290 ) / 133980
= 924 / 290
= 924
Step2:
LCM(2, 647) = 1294
GCD(2, 647) = ( 2 x 647 ) / 1294
= 2 / 647
= 2
Step3:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
So, Greatest Common Divisor of 924, 290, 647, 221 is 1
