Given numbers are 658, 222, 782, 253
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(658, 222) = 73038
GCD(658, 222) = ( 658 x 222 ) / 73038
= 658 / 222
= 658
Step2:
LCM(2, 782) = 782
GCD(2, 782) = ( 2 x 782 ) / 782
= 2 / 782
= 2
Step3:
LCM(2, 253) = 506
GCD(2, 253) = ( 2 x 253 ) / 506
= 2 / 253
= 2
So, Greatest Common Divisor of 658, 222, 782, 253 is 1
