GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 292) = 46720
GCD(640, 292) = ( 640 x 292 ) / 46720
= 640 / 292
= 640
Step2:
LCM(4, 114) = 228
GCD(4, 114) = ( 4 x 114 ) / 228
= 4 / 114
= 4
Step3:
LCM(2, 820) = 820
GCD(2, 820) = ( 2 x 820 ) / 820
= 2 / 820
= 2
So, Greatest Common Divisor of 640, 292, 114, 820 is 2
